I know this has been covered many times, but which heads are better? Trickflow or Livernois heads? I was thinking about buying stage 3 heads from Livernois, but I have heard that they are ported heads for my new edge Mustang Gt and that Trickflow heads are way better? Is this true? When the time comes for me to build my engine, should I just buy a shortblock from Livernois and then buy a set of Trickflow heads??

what comes down too is how much air those heads can flow...I believe the TFS heads flow a lot.

I would go TFS! Good room to grow and a great head to start with! I have them and love them

I've seen some back to back comparisons of stock PI head and TF head where the TF did lose a good bit of low end power, but was certainly made up at the top end. If it was my car I would go with the Trick Flow unless the Livernois heads were a lot cheaper.

For the money spent on a Stage 3 ported Livernois head, you could get better flow all around with a TFS head for almost the same price. A typical real world flow # of a Stage 2-3 ported Windsor/Romeo head is about 219-223cfm using a 3.552" bore. A TFS head will hit 238-241CFM on a 3.552" bore. A TFS head on a 3.7" bore could hit close to 250cfm on the right setup.

Mr. BMR. That setup works, so there's no need to try a TFS head, but if that setup had some slightly cleaned up TFS heads, I would guarantee the car would pick up even more.

Trickflows flow better hands down.

Our heads not only flow better but also look at the other benefits of the heads. You get a better casting, 3/4" thick decks, a revamped oiling system and the replacable cam caps, just to list a few.

? This is confusing me.

I need a set of these on my little 2 valve.

save up for awhile and get a set of fully built and ported tfs heads if you want the best of the best

TFS heads(stock) flow better than any (stock type) ported head that I have seen . Porting the Tfs head NOT worth the money unless you have an engine to take advantage of it (Big Bore).

Also with some turbo cams designed for the tfs head.

I had my 44cc heads ported by Fox Lake with a stock 01 cobra aluminum block and VT stage II cams and put down 355 hp and 350 tq through an auto......I basically ran out of intake at that point........I will be working on an aluminum 5.0 block with a stroker kit for 326 ci..........my heads flow 260 cmf @ .550........the heads are amazing........I am hopeing for 420 hp with the new set-up.....I had a friend due a similar set up with a 5.0 iron block from Ford Racing and 324 ci with stage 4 cams and bullet intake put down 398hp........I am just looking to see what I can get out of the block.....355 hp on stock bore was pretty dang good......I could have went with a bigger intake but being an auto I want to build peak power at 6250 rpm....that will put my shift points around 6500 rpms.......looking to go mid 10s all motor....should be cake with the new set-up.......I ran [email protected] with just DRs..........1.56 60 ft.....3100 with driver.....

Thanks for great information Yellow02GTauto! I read about your setup from other mustang forums and had no idea you were on here. I am trying to do a top end build on my 96 GT which has currently 97k on the clock. I feel like its fresh enough to handle TFS heads with VT/CMS stage 2 cam because I want to get into the 12's all day with this setup. Your power numbers give me hope that there is a lot left on the table with a combo like that. What is even more impressive is that you made those numbers through an auto! WOW! :rock: I could imagine what this setup would yeild with a better intake manifold. For example, maybe a Logan sheet metal intake for maximum air flow, but it cost like 1200-2000 dollars for it lol. What was the final compression on that combo you have now? Was it more about peak power or a nice broad power band. Just curious, because I really want to do the same thing!

 

[Yellow02GTauto]

I believe the compression was 11.7 to 1 with the cobra -2.3 cc dish pistons......but I changed the cam profile to MHS stage 3 cams and it brought my shift points to 6500 and neted 116 mph throught the traps..I believe the CR with the cams bled down to 11.2 to 1..or close enough......pump gas was perfect with the combo and with the TFS heads it put down a total of 23 deg of timing.........it all depends on the intake you use......with the PI intake and 78mm BBK TB combo I believe is the best.....adding some cubes will be the best bet but I will never run a metal intake again as I have tried 2 different ones and had them dyno tuned and the PI set-up was the best with the auto as it always produced more TQ and kept the shift points safe for the auto.....you can't really rely on the auto past 6800 shifts........I am working on building a set-up that will produce over 400 hp all day N/A......its all about the cubes at this point....if you have a good Manual Trans and want to spin to 7500 I would suggest the TFS Intake as well.......

 

[JerZeyStangz]

Good info. MHS sells the ported PI intake and the bbk 78mm TB combo. Those parts match with the heads and cam will make some good street power.

 

[Todd Berry]

P.m me a price on heads for a turbo set up please

 

[mike02peterson]

Thanks everyone for the reply. What are the best Trickflow Heads that I can buy. I was thinking about the Trickflow Twisted Wedge Cylinder Heads 38cc. Also, is it worth to have them ported if you are building a motor that can support 600 horsepower?

Thanks

My old car just laid down 775rwhp with out of the box TFS heads. 26psi. With even more potential in the future.
