NO

You need to measure and flycut the pistons (if necessary) if you're planning on running ANY type of milled/large valved heads with ANY cam.

No doubt about it you will have to flycut and alot at that. If you dont there will alot of noise on first startup along with alot of bent valves and prob spun rod bearings .

Thanks guys...I currently have a cam but its not as large as the MS4. My current cam is only 580ish on the lift. with a 240 duration. Im gonna measure it but was debating on going bigger and did not want to buy another cam and it not workout.

I just bought the MS4 and have PRC 5.3 2.5's milled to 59cc. Clearance is not even close. You need to flycut. I was told by TSP to go .100" on both the intake and exhaust if that helps.
