Yea I am happy to hear my current trex will match well with these heads bc I am on a budget and if the car runs strong and makes good numbers at the track and I can save 400 bucks I will be happy. If I dont run the times I want I will then have a custom cam installed afterwards.

 

Check with Vengeance Racing they have some excellent cams and head packages, I have the 220 heads and a vrx5 cam, Its been Proven to put down 500 rwhp on a 6.0 with a Fast 102 intake.

 

Thanks man

 

I also have the 220's cast heads from trick flow. I am only putting down 426/414. My cam is the vrx4 which is 228/230 .588/.592 112 LSA. Do you think the cam is what is making power so low? LS6 intake btw.

 

If you are an a4 that is about right. My tfs 220's made 434/400 on my a4 with a 90/90 and 230/234 cam...

My car is supposed to be going in for a cam change. But will ask shop to do a pull before. I won't be home for about three more weeks.

 

440/400 here with 220's and the Polluter(242/244). I really feel the LS6 intake and Pacesetter headers are holding my combo back.

TEA will touch up the 220's for $200-$300 so they flow very close to the 215's. I wish I would of originally done that.
