PRC LS6 2.5's question im looking at a set of used (3,000 miles on them) PRC 2.5 LS6's. my question is they are milled to 61.5cc....is this a good choice over PRC 2.5 5.3's in a street/strip LS1 f-body? im gonna be using a cam similar to a torquer v2. thoughts?

the 2.5 ls6 heads are better heads then th 2.5 5.3 heads the flow a little better ad have a better combustion chamber design the only advantage with the 5.3 heads is a bump in compression but with the ls6 heads being milled it wont be that big of a difference

thats what i was concerned about. im still very new to this game, but have a good background in auto mechanics. i had a friend tell me that the 5.3's would be a incress in compression as well, but i wanted to make sure with these being milled to 61.5cc wouldnt cause any trouble. and i plan to run a 100-150 shot later and dont want these to cause any issues because of to high compression.
