Cam Question.

Heres a quick scenario, a true scenario, but a scenario none the less. What should I do, or will I even have a problem..

Stock LS2 shortblock (20K on the clock)
Patriot Stage II LS6 heads, milled .025 (2.02/1.57)
Custom Grind Cam 236/248 .601/.615 on a 110+2

I'm almost positive I will have PTV issues with the milled head and that cam. My question to the motor gurus, should I cut the pistons, or sell the heads and just buy an un-milled set from Gunnar? Will I have issues with an un-milled head as well, or will I be good?

Thanks!

Your already going to have the heads off, so milling isn't as big of a deal. Some of the older Patriots had the chambers welded and re-milled, so they didn't need to be milled on the bottom. If you could swap yours for them, that would be easier.

Flycutting will be in order for sure.

For which head setup? Milled, un-milled, or both?

The TRex fits with stock heads, and its 242/248 110. So its possible your cam will fit. Either way you need to check it. Might be better off just flycutting.

I had planned on spraying. I'm not all that cracked up about weakening the already weak stock pistons. Is there a write up anywhere for fly-cutting? For some reason my search is acting all funny.
