Default Need a little guidance on compression

Here's my dilemma. I found a pretty good deal on a set of ETP heads but they're only 62cc chambers. This would raise my compression from 8.3 to 9.0 My setup is a 408, 242-238 cam, S91 OFI kit. Car is mostly a street car with occasional track use. I'm planning on going to AFR or ETP heads eventually for the thicker deck. I just have patriot 6.0's now.

9.0 should be fine, especially assuming you have forged internals. it will just be a little snappier, and spool a little faster. you'll like it.

if you want to sell those patriots, lemme know. im lookin to buy quick!

I totally agree with this.
