Howdy folks, I would like to get some input from all of you.
I just picked up a set of 440source stealth heads for my 440, that will be replacing a set of 516. What I would like to know is- How much should I have milled off to have my compression ratio at around 10.5 to 1 and not need to mill the intake ?

Here's a little bit of info on what I will be working with.
440 bored .60 over
Stealth Heads at 84cc
2355 pistons at .009 down in the hole
Head gaskets from 440source .44 compressed. I was going to use the felpro 1009, but there will be a little bit of over hang on the ring in a couple spots.

I could sure use some advise on this. Let me know if I need to provide more info.

Thanks in advance.
