236/242 .580/.590 on a 112 lsa can this be used with stock ls6 heads and springs?

I would put better springs in there but people have put bigger duration/lift on ls6 heads before and made good power.

def need springs anything over 550 lift and the springs are not going to be enough and a valve is going to kiss a piston.

Comp 918 springs good enough?

918s would be one choice. PRC duals would be a little bit extra insurance.

I am using 918's with a 233/236 w/ .592/.598 with no issues. But I only have a few thousand on it so far, but it has been run hard at the track a few times to the rev limiter on Stock LS1 heads.

great cam choice, go with a higher lift like 615/615 and use the prc duals. i run this cam and have gone 11.5s, cam only
