Heads & Intake
Hey
I am looking at changing my heads and intake this winter. I was looking at the trick flow 23 degree heads that have been cnc ported with a stealth ram intake. My motor now has 10.1 compressiong stock intake and cast iron heads 194 150 valves. How much more performance could I get by swaping heads and intake. The car runs 13.5's as it sits. Any other head options would be great

What is the chamber volume of the TF heads you intend to install? If you have 10:1 compression now with 76cc heads, you'd better get the 72cc TF heads.
It should be a very nice pick-up when you get it sorted out.

I was planning on going with the 72cc heads. The compression will be more but since I will be using aluminum heads I should be ok.
