LS6 Heads Chamber size? What size are they stock?
What would 60.5 bump the CR to with a stock bottom end and GM head gaskets?
Need some info right away, thanks <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: LS6 Heads Chamber size? Cool, thanks guys.
I got these heads already ported but never run. The guy said they werent milled. Had them flowed this weekend and also had the chambers checked and they measured 60.5
I'm still gonna get them resurfaced minimally so I'll be at around 11.0, thats exactly where I wanted to be at <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: LS6 Heads Chamber size? I would feed the motor more cam. Especially with the higher compression and the better breathing LS6 exhaust. Should be closer to a 224/228 .580 lift on a 113 LCA.

Plus I want this car to be VERY streetable since I only make it to the track 3-4 times a year.

GM lists 98-01 and 02-04...can't seem to find a difference, furthermore I thought 01 and 02 heads were cast the same, just with a diff valvetrain.
Thanks,
