Default Trex and TFS 215 can it be done
I was looking at using the TFS 215s on my 346 and using them with the following combo...Ported fast 90, kooks 1 7/8 lts, EWP, UDP and Trex

I tried a search and havent seen anything with this combo. would PTV be an issue with the angle of the valves with the TFS heads?

any insite would be appreciated

Those heads would gain you better PTV clearance than the stock heads. So yes it can be done. No idea on how much clearance though.

Just make sure you have at least 11/1 compression with a setup like that.You will want to mill the heads to do that and will probably have to flycut,but it will surely be worth it.

Geoff, that's his screen name also.

He's at Thunder. Shane, too but I don't remember his screen name. Great guy's who will answer all your questions.

At least they were, I've been off the boards for awhile...

TREX is meant to fit under stock heads without flycutting..

Trick flows supposedly have more PTV clearence than stock..

Just based off these 2 things I would think it should fit fine.

BTW sounds like you would have at least a high 400whp combo there. On some dynos you might hit 500whp. Would be a strong runner for sure, but will cost you a pretty penny.

Sounds good, get it together ASAP and throw it on the dyno and lets see what she does.

Would be good to see track times too. Good luck with it.

Im sure they fit no problem. Just dont mill them. As someone said they offer better PTV clearance than stocks and the Trex will fit with stocks no problem.

12bolt good for auto, 9" better for 6speed cause of the shock from the torque arm

+1 12 bolt may suck up a little bit less hp but its deff not bullet proof where as the 9" is.
