Heres what I found doing a search and LPE commenting here on tech
heads are made in 2 versions, a 60cc and a 62cc chamber. The 60cc chamber will give you about 11.3:1 compression on a stock bottom end. Flow numbers:
Int. Exh. 200 150 117 300 225 168 400 273 202 450 285 210 500 291 217 550 304 221 600 311 222
They still use the LS6 sodium filled valves, stock size, and LS6 valvesprings. The 60cc versions have been milled approx. .055" to achieve this chamber size, so you will have to notch the 4 corner bolt recesses to make your intake fit, but it's no big deal. Over all, a very good set of heads for the price considering your getting new, genuine GM LS6 heads, CNC ported for about $1900.00 outright
