misinformation from past posts its my understanding stock ls1 heads flow about 235 cfm, stock ls6 about 265 cfm. ported ls1 between 280- 300 max where as ls6 w stage 2 320 plus. i have budget ls6 stage 1 which TSP claims flows 307 cfm i didnt think i needed more than that. (i paid $900.)
ls6=250
5.3 4.8=221
6liter 317=245
all at .600 on the intake and all flow close to the same on the exhaust..
you will see nice gains if material was taken from the right places in the runners....i say go for it..

We offer cnc porting of our customers castings for $600 with valve job & decking! For a budget setup that's a good option, but really the PRC ls6 heads are outright for just over $1000. When you consider your getting proven performers with new castings it's pretty hard to beat! Besides you can then ebay your stock heads for 100 bux or so & be in a set of good quality proven heads for under $1000!!
