Corvette Performance - GMPP LS6 cnc's heads part#88958665 vs 88958662

Which would be best for street application w/ a LFE GT2-3 stealth cam for 01 Z06. Want to run on regular 93 octane pump gas with no problems on totally stock bottom end etc. Going with these heads b/c of warranty. Need stealth.
Thanks,
Kevin

these are the ones i am looking to buy, but don't know if they are not right for my application:

part# 88958665
Chamber volume 65cc
intake valve 2.000
exhaust valve 1.550
installed height 1.800

You definately want the 65cc versions, that will put your compression ration close to stock. The 60cc versions will put it over 11.2:1 which would be too high for street use on pump gas. I think we spoke on the phone today, but let me know if I can answer anything else..
