Super Stock

172cc Super Stock Head

[@mikef-gi2dg]

I started going to national and divisional events in the late 70's. I love Stock and Super Stock. These guys and gals work the heck out of this stuff like no other. This is some of the most in depth S/S tech I have ever seen. When people talk about starting to drag race, I say go watch a bunch of Stock and S/S racing, look over the cars, watch the competition, then buy a rule book, and be amazed. It's not about throwing a bunch of parts together from a catalog. If you pay attention, you can get great performance if you work the combo, not just throw money at it.

[@troymecey]

Other than the shape of the intake port, it reminds me of the old Grumpy Jenkins raised ports. Nice work, Chad.

[@rodneybyrd9516]

LOL-making a W2 head for SBC! NICE WORK!! Love it!

[@rickgehring7507]

I noticed that also....hell for a while the Hot ticket for the SBC was the Mopar SB 420 intake.

[@ericscrutchins6350]

Yeah how about that just like the W-2 valve angle that Chevy uses also, I've ported lots of those W-2 heads and intake manifolds over the years for a long time friends Mopar drag car

This’s why the Cleveland 4-V iron closed chamber heads with the Parker funnel web intake with the tongues is such a awesome setup. The tongues raise the floor of the intake runners giving it a straight shot to the top of the piston. The camshaft that I’m running is a 0.711 intake and 0.714 exhaust. 262-272 @0.050 and 300-312 advertised. 4150/950 Holley. My 81 Capri went a best of 6.09 in the 1/8th with 1.26 60ft on a 175 shot. The car had 4.30’s geared for the 1000ft. I refreshened this motor and went with 0.050 longer Manton pushrods and got the midl lift geometry corrected and it’s going into my 86 mustang which is about 400 pounds lighter than my Capri and it’s all Team Z suspension. I know that I can get high 5’s with this Cleveland.

[@supertruckertom]

That flow was amazing for the port volume and lift.

[@BassanettiEngines]

Great job and thank you for sharing so much knowledge

[@manitoublack]

What gets me is. Why don't the NHRA scan a bunch of heads in the class. Pick one that's in the good but not great category. Then provide those CAD files to the head manufactures so they can produce 'as-cast' versions that would be the same across all foundries. Would save a bunch of cash for punters. And just tighten up the rules around what porting can be done for parity...

[@yarrdayarrdayarrda]

Class heads like these are pretty much custom for the application, and I doubt you would find one car owner or engine builder/head porter that would agree to give up any dimensions (advantages) of theirs. The bulk of the "punters" can buy the proper head for their application, and better suited, from any number of manufacturers, and if they want something more specialized, from any number of porters.

[@INFANTRY1981]

That would put alot of small business in a bind. Don't think I would support that.

[@reillystsb]

I seen stuff like that at High Velocity heads back in the 80s you know Joe patelli the guy that designed the Victor and Victor Jr for Edelbrock

[@terrywilson581]

Yeah you're all right about all of them passing away and a lot of them have no idea how to do it they watch KZbin and go always scratch it around this ought to work now they just get that CNC ported and it's all done with an LS but yeah really enjoyed that little video that's that's nice work 💪💪💪💪💪💪💪💪💪💪

[@dennisrobinson8008]

Similar work is done on 4v cleveland heads. Epoxing the floors and raising the roofs.

[@DURRIESVISION]

Absolutely kool heads and great info, thanx for that. from the land 'Down Under'... Oz 🇦🇺

[@jmoemorris4133]

Interesting, I am doing a dogleg 4 valve Yamaha head that I am configuring in the same fashion. Bad ass you got going on there!

[@slickrick5735]

Those tilted intake ports look like they’re based on a Vortec design.

[@garykarenmcgruther6386]

You have any pictures of your Iron SuperStock head's? To me that's where the men separated from the boy's. I know the Aluminum heads have better port's to begin with by design. My hat goes off to you Sir. Iron is a Bixch to work with.

[@ericscrutchins6350]

I agree, everything is aluminum these days no one wants to tackle iron heads I guess that it's very time consuming but the results are well worth the effort, there are a lot of nice iron super stock legal heads out there that won't need too much work to put them in shape for competitive use I like those EQ iron heads myself and I do believe that they are NHRA legal for super stock

[@dondagy9109]

Nice work.

Good job showing telling,and thanks to you have a great day see ya bye bye.

How do you get the knowledge to attempt to do head work? want to race super stock vx with Volkswagen head.Have to do the same type of similar work.

[@skipper6567]

so cool 😎Thank you

[@GidDree]

Is it above 370 cfm @700?

[@David-tv3mg]

What epoxy did you use to fill in the port?

[@8mywal8]

How does the epoxy not break off with heat causing expansion of the aluminum

[@thereluctantgearhead4544]

It's tough shit....

[@stevesolo16]

What happened to the roof in the intake bowl? It looks a mess around the valve guide.

[@SpeierRacingHeads]

LOL. OK boss. Never seen a SS head have you!

[@INFANTRY1981]

Well, its not cheap to go racing. The SS class(s) must do more with less as you said. But in my mind its morphed into doing more which costs the most money. 50+ hours on heads just not affordable I think for most and I think most may agree - pit talk... Great work by the way - awesome! However NHRA has class racing just about anyone can run with just about anythiing, it just may not be competive in No-Breakout class eliminations... Its all good though - take the non-compete car grudging or betting on a SPREAD ET or Drive and Drag. All kinds of ways to take a non-compete car YOU LOVE and WIN w/o Street Racing it.

[@boharris8179]

What epoxy is that n where can I get it

[@SpeierRacingHeads]

Z-Spar. Any marine store.

@@SpeierRacingHeads Do you do iron heads?

[@ricvis44]

I’ve got a question for you! I have a 4.3 Vortech V6 that I took out of my blazer. I thought it was ruined but it’s perfectly fine. So I was wanting to modify the cylinder heads to get more flow. I wanted to put the cast-iron heads in a grill and heat them up. Then I was hoping that I could use my Mig welder to build up the area around the intake runners. What do you think about this? Will it leak? I also wanted to make my own intake manifold. Probably start off with a 750 Brawler carb. Comp cams hydraulic roller cam shaft. .500 lift etc…

[@yarrdayarrdayarrda]

The grill wouldn't get them nearly hot enough and the head will crack right next to the welding. (dissimilar metals as well, being cast iron and mild steel for the wire) I would bet the seats/valves/bowls would need to be heavily worked in the right direction before the intake ports become the restriction.

[@thenewBH]

Might work with silicon bronze wire.

[@ericscrutchins6350]

You can't mig weld cast iron at any temperature it's just not possible, now if you know what you are doing, you can do some furnace brazing with brass brazing rods like a lot of the super stock head porters are doing but the cheapest thing to do is get some Goodson epoxy and form the ports yourself and grind them to the final shape, or if you could find an industrial company that does cast iron spray welding that could be done also, but you would have to show them where you need the welding done and there's going to be lots of remachine work needed after this work is done so actually to avoid all of this unnecessary work you might be better off finding a pair of bowtie V6 aluminum heads which will out flow any stock V6 head out there, match the right roller cam to the application and you should be in great shape

[@ricvis44]

@@ericscrutchins6350 going to try brazing with my TIG welder on cast iron. I have MIG welded a cast iron pulley at the place I worked. An envelope machine. It was a government job that had to ship so it was worth a try. I had my supervisor to heat the pulley and jerk back out of the way and I welded an inch at a time. The pulley stayed on the machine for another year. We got lucky.

Super stock rules specifically state. No porting allowed outside of original size. Gray area.. raise the port and add epoxy. Port is still original size! Nothing new.. Bill Glidden was famous for doing it on ford heads.

[@SpeierRacingHeads]

Nothing new.. But things are better, making more power, flowing more air, than they ever have. All because the OEM stuff is used up and they are allowing NHRA approved castings.
