Default Biggest Cam With Milled Heads????

I have LS1 5.7 heads that have been milled .033 with 2.02 int. and 1.57 ext. valves. I understand that I would need to check P/V clearances. But I am curious how big of a cam could I use with these heads? I am currently running a small 218/224 567/567 113 cam.

Kinda had the same question, but the opposite. How much could I mill off the head with 578./.584 lift.

At least .030 if you have stock sized valve, atleast thats what Ive seen from others.

I would say 226 or perhaps 228 with .59x lfts max. with standard gaskets.
