compression ratios

[white95]

I bolted a set of d0o3-c [69-74 vintage 351w heads] heads on a stock 94 motor. I'm curious if they'll bump the compression up any due to the 60.4 cc chambers. Aren't stock e7te heads cast with a 62 cc chamber? I'm not expecting much [if any] hp gain from these heads, but they were fresh, and available. [and free]
