Trickflow's Ford 4.6 2V Mod Motor cylinder head.. Their Best Ever???

These heads gives best performance for a 2v but also they have benefits for safety of the engine. Have them for 6 years. Never had a problem.

Are the spark plug threads different than stock??

[@christophermonroe701]

​@@dannymckinsey208yes, they are deeper and have more threads to avoid that spark plug blow out issue.

[@neg4t1vezer04]

​@@christophermonroe701 Was that an issue for the 2v heads? I knew it was an issue for the early 4v C heads and the 3v truck heads.

[@antonioalbarran6040]

​@neg4t1vezer04 3v plugs get stuck in the head from corrosion. They break off directly where the probe shank meets the thread. 2v heads are the plug poppers.

[@billfioretti3013]

Nice piece and more to come! Thank you Andy for bringing us "older-timers" up to date with the latest technology. Though the 4.6 2 valve may have lacked some grunt as delivered it did offer reliability and longevity. Ford haters out there say recent and current Ford engines are unreliable compared to competitors production offerings. WRONG. Many 4.6 2-V's are still on the road today and running with well over 300K original miles. I for one love my daily driver decommissioned 2004 P71 Crown Vic!

[@UnityMotorSportsGarage]

Bill you are exactly right... The 4.6 will last forever if you maintain them! Thanks Again, Andy

@dannymckinsey208 it will definitely cure that issue as these heads have full threads on the plugs! Plus you will get a nice bump in performance also. They come both in 38cc chambers and 44cc chambers Thanks for watching Andy

Two out of three of those engines don’t have the synchronizer problem and the 5.4 can be fixed. There’s a lot of those engines floating around.

I'm working on a 4.6 2 valve with a 2011 crown Vic my opinion will be the 2 valve heads can do work with boost and if you are DIY Porter you can open them up yourself without paying the massive price cnc porting Spend your money on valve springs and cams you're short block and find a way to boost it ez 700 hp

[@sategllib2191]

People have made 800-900hp with stock heads. Idk how long it'll last lol

[@bobkonradi1027]

I note that you and D.V. have ported the head. It is a pet peeve of mine that the cylinder head manufacturers send out their product with a requirement to port them to get the best performance. What my thought is, is to get a set of prototype heads, before making a production run, port them for the very best airflow and performance, and then send them back to the company. The company then would take the heads, revise their molds to incorporate the mods the porter did, and then start production runs. The way it is now, a set of aftermarket heads costs $2500(+), then it costs an additional $1700-2000 in porting costs for a total investment by the buyer of $4200-4500. If they would take the time at the design and foundry level to put out the very best product that the mind of man could come up with, it would be a great help to buyers of the product. Changes at the foundry level are minimal to the manufacturer. For instance, I bought a set of aftermarket heads for $2800, then there was a combination of airflow work and port grinding for another $1800, for an investment by me of $4600, when, if the company had taken the time to "pre-flow" the heads my cost would have been just $2800 to maybe $3000 at the most. Every head test I've read, the first thing a buyer has to do is get them ported to compensate for the failure of the manufacturer to produce its best possible product on the go-in.

[@UnityMotorSportsGarage]

Bob, these heads Unported will support over 500hp NA from a 4.6 and are very efficient. If you noticed I said in the video that these heads do not need porting for most apps. But we have something special in mind with this crown vic. Thanks for watching Andy

No. TFS heads repositioned the intake and exhaust valves. The geometry is not the same. You would have to acquire TFS specific camshafts for the setup to run 100% and properly. Installing pi cams will allow it to run but not give it the performance your spending all the time to achieve

I've got a 4.6l 2v question for you Andy. I'm building budget 4.6 for my 92 crown vic, I'd like to know how big an intake valve I can put into a PI head without having to cut a stock flat top piston. I'm using Cushman stage 2 PI NA cams (you recommended them to me a long time ago but I haven't done anything with them because only just recently did my Vic jr. intake show up that I had on back order for over a year) and I'm doing my own port work on the heads. I won't be starting work on the engine in earnest until after the Mid America Shelby Meet (too much other prep work).

[@UnityMotorSportsGarage]

John that would really depend on the shortblock you are using. A non-pi piston has a 11cc dish vs the PI piston of 17cc dish and the first place the valve makes contact with the piston is on the edge of the dish.. If it were me I would mock it up and check it to be safe because with the Cushman cams the PTV clearance is on the smaller side.. Sorry i can give an exact answer but I hope this helps Andy

[@johnflett2531]

@@UnityMotorSportsGarage Thanks Andy! The short block will is from a 96 cobra, I'll be installing a new set of gen 2 (2015 up) Coyote rods and most likely flat top pistons out of an old Navigator engine (I'm a little undecided on that part, I might end up using the 3cc dish pistons out of the 4v 4.6).

Does 3 valve have anything on 2 valve in practice or is it better to jump straight from 2 to 4? Since you know Mr. Vizard, could you ask him if it's possible to design a 3-valve system that is superior to 2-valve and verging on 4-valve? IE, is it possible to run something similar to polyquad? Furthermore, on paper, I originally thought 3 valves could get within 10% of the valve area of a 4-valve, but that was before factoring in a spark plug hole. After I did that, 3-valves were barely above a 2-valve on the same bore. However, if one were to use a twin-spark design with the spark plugs below the intake valves and adjacent to the exhaust valve, you could theoretically use the configuration I originally had on paper, putting 3 valves VERY close to a 4-valve setup in terms of total potential valve area. Just food for thought. If Trick could do something like that with custom 3-valve heads, we could see Coyotes being dethroned by their older cousins. But even more of a pipe dream, we could see pushrod engines somehow retrofitted with 3-valve heads to bring them into 4-valve performance territory. Another upside to 3-valves based on the (admittedly limited) ones I've heard is that engines with only 1 exhaust valve tend to have a deeper, smoother exhaust note.

[@paulmryglod4802]

The 3v flow waaay more in mid lift to 0.5" compared to any stock 2v, both intake and exhaust. For the street, they're fantastic because you wont be running a cam much over .5 I think richard holdner has a dyno overlay and flow bench overlay showing this

[@Drunken_Hamster]

@@paulmryglod4802 When you divide one valve into two, the max usable lift changes a lot. Most 4v engines don't go much above 0.5" simply because that's already so far past the 0.25 to 0.3x the diameter measurement which would give them "the same" flow as a port completely unimpeded by a tappet valve. Either way, I'd still like to see a perfected factory casting 3v vs David Vizard's perfected Trickflow 2v and then, if possible, compare a "perfected" aftermarket casting 3v setup, potentially with twin spark and a quench shelf (like Mercedes 3v heads) in order to get more valve area and less shrouding of the intakes.

How often have you played with a hybrid PI engine? The ole Non Pi head and PI head

[@TecniclyAwsm]

Honestly those Trick Flows are great...but it sucks nobody makes a head except them. 1 brand or ported stocks and that's the end. I still have my 02 GT trying to make power and there's very little help when it comes to heads, Trick Flows or nothing. And a set with cams is 4500 or so..which is nuts. You may as well motor swap for something (as bad as I hate to say it) better than a 2 valve. Single turbo the stock motor for a grand with some fuel system upgrades and forget heads with a 2v if you ask me. It's the only way you're affordably making power. Or go drop 10k in a 2 valve to make 400hp...it's up to you

I am in middle of a 4.6 2v build right now and because of your suggestion about carburetor swap I just ordered a Victor jr intake and the MSD Mod 6 ignition box but unfortunately because when I went to buy head's during COVID I couldn't find trick flow head's in stock anywhere plus I had already bought MHS stage 2 NA Cam's with the degree service and really didn't want to change Cam's after spending all that money so I did purchase a Set of Promaxx shocker head's which are Fully CNC ported and at least solve the spark plug thread issue so now with all that said this car also has a 150 shot and pretty much everything else upgraded also only Need a Carburetor still what's your suggestion on that ???

@@UnityMotorSportsGarage Well, you DID point to the TFS head and say fourteen because of the 34cc chamber. In any case, my daily driver is an '06 CVPI with 85k on the clock that my sheriff friend bought new for his own personal use. I also have a '97 with 110k. Is that a better engine to start a build with?

[@UnityMotorSportsGarage]

With the stock 17cc chamber of the '06 short block you would be around 10.5 to 1 if you use the early Non-pi shortblock with 10cc dish the compression will bump up to around 11.25 to 1

I've made well over 600 NA out of a 2V so they can make power... But with these heads out of the box I made 425 at the wheels.. I don't know what they are making now days Andy

[@rumblecanada]

I'm building a 4.6 2v with 2 paxton novi 1000 superchargers. It's on youtube. My channel is RumbleCanada. My plan is 20 psi @ 6500rpm. On the dyno with 1 paxton novi 1k, it made 394rwhp at 6k with a safe tune. For me, the 4.6 2v needs boost. Thanks for the info. I'll be watching all your videos.

[@UnityMotorSportsGarage]

I made 425rwhp with these heads out of the box with a Carb NA back in the day then later with a 304" big bore made over 600hp on the pump NA on a 250 shot would run mid 8's @ over 150 mph Andy

[@rumblecanada]

I'd love a set of trickflow heads for the 4.6 2v. Not sure if they would work with my comp cam 262ah and AR 1-7/8 long tube headers? They are going in next after I dyno the twin superchargers. I want to see what happens with 2 superchargers on a stock motor with a safe tune. My 394rwhp only had @ wot 10 or 11 deg total timing at 11 psi. 600hp would be sick for a 2v

Even he will tell you that he couldn't have pushed into the 4's without the TFS heads.. on the other hand once you go from 5.70's in the 1/8 to the 4's you will find everything wrong with your setup because the power needed to drop that kind of et is unreal at that speed Andy
