How much can I get LS1 or 5.3 heads milled so that I don't have to cut the pistons on a stock bottom end w/ a TSP 231/237 595/598 112 LSA?
TIA

basically none other than a light resurface, you are about at the minimum "safe" limits with stock heads

 

??? sure about that? i've seen plenty of guys runnin aftermarket heads with that cam. PP "ls6" heads included.

this is one of the bigger cams that still has pretty decent PtV clearence...thats why those who want to keep their PtV for milling or whatever reasons, and want a big cam, stick with this one instead of the trex or g5x3 or magic stick.
