Default Clearance issues with T-Rex and milled PRC's??
Going with a T-rex and looking at a set of PRC stage 1 LS6 heads which have been milled to 58cc. Seems most people have had good luck with the PRC's and T-rex with not having to fly cut. With the set I'm looking at having been milled to 58cc, will that ensure I am going to have clearance issues with the T-rex, or may I still be safe?

i would say so. You must absolutley check to make sure, but i can almost bet, you will be flycutting the intake side.

Have fun flycutting
this is where the ETP heads make for a killer combo.
You can do 58cc's with a set of 215 ETP heads and more then likely not have to cut.

What kind of compression are we looking at on a stock engine?

I have a TRex and PRC heads milled .030. .045 gasket and had to flycut. It's not that hard to do...

I would also think you will be pushing it on the CR for pump gas.

Ya you will need to flycut! Why wouldn't you seeing as the heads will be off anyways ?? Just be safe and flycut so you know you wont have to worry about it. Bc if the piston hits a valve it could jack your new set of heads up .
