440 problems (take 2)... More known values

Haven't been able to get ahold of the stuff to check the cc of my heads. I plan to do so eventually. Is there a way to check if these heads have been milled with a micrometer? I know checking the volume of the cc will tell me this, but I won't be able to check that for awhile. I would like to check to see if they have been milled, that way I can get pretty close with the static compression. Like someone explained before, no way to accurately find the dynamic compression without ALOT of $..


I called a couple cam companies and got two different answers.

Here is one - http://www.summitracing.com/parts/cca-23-225-4/overview/

the other - http://www.summitracing.com/parts/cca-21-305-4

Sorry, but to me 222 vs 240 @ 050 is a big difference. But will it make a big difference in sloppiness?

What is you guys' two cents? One of those cams is a 1 bolt cam gear, I have a 3, so I need to find the alternative.
