Hey guys as the title states I'm doing a 402 stroker kit on my 06 ls2 with the addition of an A&A ysi kit. The car currently has a comp cam 231/239 .617/.624 113 lsa cam in it and I'm laying down 486. With this cam the ptv clearance is very tight on the setup I have now. If I do a 402 stroker kit will I be kissing the valves or am I missing something here. Will it work or not. Thanks guys!!
