good to hear soldier! cant wait to see it done. so what are you doing for the retune, just gonna up the boost a tad and add the headers? you should invest in a set of cams man(while it's all out anyways). I'll make you a good deal on my mhs's with the springs and intake valves necessary to run them if you've got any cash left over!

10:1 compression with boost is nothing nowadays. My one buddies car has 10.2:1 with 14lbs thru an f1r on pump gas. and look at all the new 5.0's, they're 11:1 and doing excellent with a decent amount of boost.
You're also talking about good flowing 4v heads not craptastic 2v heads. The better the heads flow the easier it is for an engine to make power safely. Why do you think 05-08 mustangs can make 500rwhp safely with the exact same short block as 96-04 that are limited to 450.
With his stock heads he will be very limited on his power because of the CR. Plus you can make more power with less compression and more boost then you can with more compression and less boost.
