Which Cam?

Not with higher compression pistons they can't, especially with a hydraulic that requires preload. A zero deck piston without valve reliefs would doubtfully even fit a mp 509. We need more specifics about the compression ratio to give you a good recommendation. Also what are the specs on these cams?

The pistons have absolutely nothing to do with what the heads can take as far as lift. They affect your PtV clearance, but thats not what I said. I said the HEADS can usually clear that much lift.
