SBF CHI Head Review With Real Flow Numbers

I do a review of the CHI 225cc cnc ported heads.

[@biastv1234]

Thanks for acknowledging that us Aussies do get thing right from time to time 🇦🇺

[@dennisrobinson8008]

Certainly

[@elmerfudpucker3204]

My family ran Clevelands in our dirt track cars for years, starting when they first came out. We had already been running the Boss 302s for a couple years, and the 351s would walk off and leave the Boss engines, when we got them figured out. By then, Ford had the Boss 351 out, and we could actually get some parts that would work. We stayed with the Clevelands when they got so hard to find, running every conceivable block and head combo imaginable. We ran hard, and were one of the teams to beat everywhere we went. We took a lot of checkers running basement ported 2V open chamber heads, when it got so hard to find stuff in the mid to late 80s. It's great to see companies coming back around to these engines, and making some excellent parts for them.

[@WeingartnerRacing]

I'm glad to know they worked well for you. I like the heads but I know next to nothing about there shortblocks.

[@psychoholicslag4801]

I still have 2 stock bore short blocks sitting in my shop along with a pair of CJ heads.

[@sombra6153]

I’ve always gathered based on rare magazine article comments from the 80s-early 90s that the 2V heads flowed better than anyone cared to admit, at least for street purposes, though I don’t recall anyone publishing any numbers cause Windsor performance heads were starting to make their way into the market. That’s why there were aftermarket intakes at least for 351C 2V to convert them to 4Vs. I had a 71 Cougar with a 2V motor. I drove it with the 2V carb but added cheap dual exhaust and open element air cleaner with a taller filter. It acted like it wanted to pull up too, park 6k, which wasn’t healthy. Thanks for sharing your experiences.

I've been running Cleveland's or 460's since 1988. Always thought the windsors were a joke. Running 208 CHI's on a 400 in my work truck. They are awesome. Kaase sells the CHI as a branded head that flows 400 on the intake CNC'd ready to run with matching intake for around $6500. I bought mine bare for $2850. With 5 angle intake on 2.08" valve flowed 316 CFM at .500" You can get these with stock location exhaust or raised .200". Also, the valve angles are the same as Fords 4V so they work with 4V pistons. You can use 4V intakes on these but you may need a spacer depending on your particular combo. A 1/2" thick works on 400 with 2V intakes if you slot the holes and lines up fine as the 2V is almost exactly the same size. CHI has several different manifolds for the short deck 351 blocks.

The Cleveland architecture still has not been surpassed. It still has as much or more potential as anything after all this time

[@timothybayliss6680]

The biggest issue with factory Cleveland heads is how stupid big the ports are. The exhaust is awful and the intake has too much dead space. The 9 1/2° valve angle is still really contemporary it just took 30 years for someone to cast a head with the right size and shape of port

I`ve got a old set of Ernie Elliot C3 heads that are going on a windsor 427. I believe they`re 1995 era heads from a nascar truck engine and those CHI heads flow 15 to 19 cfm more except at 500 lift where they are the same. I saw those CHI heads at a PRI show in Orlando a few years ago and was impressed.

My folks traded around with the Elliotts forever. We had a building and construction business, and used George Elloitt's building supply for lumber and materials.

Happy you saw the light. LOL I have been a Ford guy my whole life.

[@donnatalielucasheimbigner7598]

Even stock 2v heads with a decent port job are EXCELLENT street bruiser heads. The heads used on the M series engines are identical to 2V Cleveland heads except that the chambers are around 78cc. They work well in a 400 though & CR between 10 & 11 is easy to do with a flat top piston running 0.007" deck clearance with a 0.040" - 0.045" gasket. The chamber is close to a hemispherical shape with quench pads parallel to the valve guide centerline, making it possible to run 11:1 on pump gas to at least 5500 RPM. I offer this because the heads are pretty easy to find in salvage yards.

[@WeingartnerRacing]

That should help the Ford guys.

[@Redneckairflow]

As a Ford guy, ford's 2 biggest issues where the shock tower cars they used. The exhaust ports are the way they are because they didn't have room for the engine, good exhaust and the shock tower. And they believed in the all or nothing mind set on engines. Look at the size of ports on all thier hp engines vs the everyday version of the engine.

[@rondye9398]

But, back in the pro stock day the raised exhaust was claimed to offer about a 10 hp advantage. Exhaust exploding out the exhaust valve at such high pressure can 'straighten' the passage to atmosphere. Intake architecture most important which Ford got right in many applications.

[@austinmclemore2821]

Pro Max offers a Cleveland head, I would love to see you do a cnc program for them. I would say it would make BIG POWER!

[@scottwilkins3170]

Its awesome to hear tou say that about ford heads! I always knew they where a step above, nice to hear someone with your expertise say it!

[@timothybayliss6680]

GM Australia also had similar port locations on their v8 engine for a while. For the v8 supercar series they were using custom cast factory heads with individual runner intakes. The factory heads went to non mirrored valve layout in 1988 and stayed that way until the Ls series replaced them, in around 1994 it was replaced in the V8 supercar series with 18° nascar style stuff.

[@dinosshed]

They did this to even up the parity. Virtually copied the ford head to suit the chev geometry as porting Siamese made it difficult. Holden also copied the watts link rear end, double wishbone front end and already had the 9 inch final drive. There was a lot more Ford engineering in the Holden than was actual Holden.

[@georgebeare8883]

@@dinosshed thanks for saving me typing up the same, lol! Just to add, back to back testing revealed the Ford head had a 50HP advantage over the Holden and Chev heads. As you say, the solution to even up the racing was to effectively make Ford heads for the GM guys. Then there was the cutting back of the Ford front undertray by 200mm to nobble the Ford's superior front end grip and the raising up of the Ford front end by 50mm for the same reason. They also forced Ford to adapt the EL aero kits to the new, totally different body shape of the AU Falcon, after Ford Legally made up a new aero kit for the AU which would have made the AU a rocket. After all of that, we have to listen to Holden fans telling us their race cars were better! Unreal.

[@dinosshed]

@georgebeare8883 Yes, I was one of few cheering on the Ford teams at a few meets, as Holden had two types of customers, #1 Bogans and #2 Old Bogans. There was no reasoning with them, as they didn't realise what they were in such love with.

[@georgebeare8883]

@@dinosshed I hear you mate! Myself and a couple of Ford mates went originally to all of the Victorian rounds of the championship. Winton, Calder, Sandown, Phillip Island, wherever a round was. It was great the first year or two, watching those 4 Falcons out front and a battalion of Commodores holding up the rear. That was before the so-called "Parity" scheme began, code for Slow The Fords Down. Talk about Bogan GM-H fans, I had a number of arguments with them telling us it was the other way around: that the Commodores were being nobbled! FFS! The best example of one of them ( who really should have known better ) happened in the workshop of a well-known drag racing engine builder. A bloke was there supplying his specialty race engine item ( I won't say what because it will identify him ) and the banter was the usual Chev small blocks are king stuff. I pointed out that the Technical Controllers of the touring cars had identified the SBF was producing 50 hp more than either the SBC or Holden V8 and so the Techies were casting up basically Ford heads for the Chevs and calling them "Holden Motorsport Heads" to fix that. Now, here was a bloke making a racing part for some of the Holden teams and he wasn't having any of that nonsense. No way! He said he was going to call a mate at one of the Holden teams and call me out on the spot. He went away in a quiet corner and called GRM. When he came back, he did not say a single word. All went very quiet. LOL. Another time, I was in the queue to get in at Calder. In front of me was John D Davison. I said G'day and we chatted. He said he was queuing and paying to get the regular event goer's experience there to compare to Sandown, the track he was promoter of back then. He was so excited for the next year's racing because Lowndes was joining HRT. He said all of the track owners were. As he put it, the majority of spectators were under 30 and drove Holdens and they didn't want to see a middle-aged bald bloke with a beard and glasses, driving a Ford, winning. That'd be JB, of course, at DJR. The industry wanted a young bloke winning in the factory Holden team car because that was good for business. That tells you all you need to know. It's such a pity that the record books show the results favouring Holden so very much, but do not disclose the reason behind why it was the case. Imagine if in Australia they "fixed" outcomes so much in Aussie Rules or Rugby! There would be blood on the streets. Cheers.

Grind the potato out of the exhaust port on a stock Windsor head now you're moving air. The reason Ford put that EGR bump in the exhaust port is so they had a place for the tooling to set on when drilling out for the EGR ports.

Hi Eric, not sure who told you that is/was a 225 head, but the 225 heads I've seen are definitely not cnc ported, and they don't flow even close to those numbers. Also, 225 heads come with 2.15" valves not 2.19"s . Mcsa is way less than your figures as well. Think someone has set you up there, or CHI have bought out a new head that i don't know about. The CHI Kaase head only has a 2.85 mcsa and flows just over 400cfm at .800 with 2.19 valve on 4.155 bore on my bench.... have to have the right shaped valve though. Chambers on them are in the low 40cc's, so really need to have the right piston, otherwise compression gets way out of control. Very nice head though.

Lol that didn’t happen. The people that developed it didn’t copy anything either they took a lot of pride in the ls architecture. There was a car mag article that interviewed the 2 lead design/developers and they addressed that rumor. Not anymore than the Cleveland was copied from the BBC heads or the Mopar Poly Heads. Though the Poly heads are rumored to be what Ford looked to in design, that supposedly from staff that developed it back then. The Cleveland block looks like an Olds V8 though… Timing enclosure and even 12-6 fuel pump holes. It’s a very finite space to fit a 90 v8 block, have similar displacement, fit between 2 shock towers/steering and use ohv cylindef heads that need to exhaust outback the side and under the car. Yes, designs ARE going to look similar especially when you got bean counters looming and deadlines to meet.

He said he doesn't port iron heads because it takes to long and teard up to many bits - he is very busy as you can see in his videos - so he looses money porting iron heads.

[@ldnwholesale8552]

Cleveland heads,,, 4Vs are so bloody big they get no velocity, the reason people have closed them down for decades. Not so bad if you turn 9000 rpm,, and that is drag race only and the Clevo explodes over 7000! Poorly oiled, cooling is poor and they are heavy. You can modoify the oiling to be ok but then the crank dia is too big so frys the oil. The M engine is worse with 3" mains. I own both!! 363 is 4 1/8 bore 3.4 stroke. Aftermarket block only. The 8.2 Windsor is a tiny little thing,, rod length is severely limited but it does have better oiling and the bearings are not near as big. Cooling is ,,, well ok. Still only has 4 bolts per cylinder head clamping so will never be a Chev. Factory blocks are only 2 bolt. Need a stud girdle for performance use. My experience is that the later 5 litre blocks are better metalurgy. And they use the Clevo firing order which is far better. The CHI heads take the best of the Clevo design and make it work. Raised intakes, canted valves, far better chamber and ofcourse being alloy make them about 100% better than the OEM head. They come in 3 base versions, 185cc, 208cc and 225cc. They can be made to go on Windsors as well but the Winsors off the shelf are only 185cc. My 208s will need the intakes ported The Aussie 302 2V head is by far the best head for street use and even then the ports really are too big!! Same size to the manifold as a Chev medium raceport.

[@too51kracing81]

I’ve been playing with Cleveland’s for 25 years and rev them to 8000 and in some cases 9400 and have no oil or cooling issues. Yes that’s after fixing the oiling issues but no big deal. And these are mostly street engines

[@ldnwholesale8552]

@@too51kracing81 Hmmm, not for road race or speedway use using moderatly high rpm consistently. Here in Oz we had them for many years after the Yanks. Were a potential explosion at all times.

BBC, SBC dominate bracket racing, then you have the trickle down effect from P/S and NASCAR. If this head (CHI) would had come out in the 70s we might be seeing a different outcome, then again Smokey Yunick had the SBC porcupine heads so maybe that would have came out of the stove pipe in the early days to compete with the Clevor. Chevrolet engine popularity and the fact that the little guy could drag race and run stock car might have been the tipping point for Chevrolet. Chevy got out ahead of the other manufacturers is all I’m saying, the ppl grasped the BBC, SBC, LS, Warren Johnson and the DRCE.

If the pilot is close enough in tolerance to the valve guide inner diameter and long enough to extend down through the guide to the topside of the guide how would anybody fight a valve job keeping it round just because your missing 3/4 of an inch or so of the guide, into the bowl area. I don't see it !!

It will kick the guide sideways in the guide. Also if you have to remove the guide the the tool the press them out will only grab the high points then try to break them off and gouge the guide hole upon removal.

As fare as factory iron head castings go the Cleveland was on top… those particular one eyed Chevy guys really don’t like to hear that.. people who build this engine are more likely to be over in their corner keeping to themselves avoiding the sh!!

You do realize CSA is the important part of sizing a port, not overall volume right? And rpm range/engine displacement dictate needed CSA. How do you know the size of the engine these are going on? 3.5 CSA is not that big for a 427 inch engine

[@WeingartnerRacing]

@@treyrags yes that’s why I showed the csa. The 2.96 is the min. A 3.5 min csa is very large for min csa on a small block. This head from measurements is fine for most applications depending on rpm. Another note I didn’t remove the corner radius so the area is actually smaller.

[@causeimbatmaaan]

@@WeingartnerRacing I realize and agree with you on the aspects of design that are favorable (big time) particularly chamber vol, splayed valves and positions but it sounded like you were comparing stock parallel valve chevy heads to that raised port closed chamber head. On a small inch [ford] I'm skeptical that it would compete with an equal inch n/a 12° raised runner sbc over the rpm range. Boosted no problem, but ultimately I suspect the exhaust restrictions kill the Cleveland in both cases evenly matched. Would you think contrary to that Eric? I know you said you liked the stability but there has to be something to the characteristics of their flow path that counters volumetric flow from being the end all on the dyno.
