The Ms4 is pretty much the biggest cam you could put in.

239/242 .649"/.609" 111

The Trex is a bit bigger on the duration that the Ms4 and people are fine running that.
.242 .248

.251 on the exhaust side is pretty steep. What heads are you running?

No, you have to check pistont to valve clearance for yourself. Dont rely on some random guy on the forum. If your engine kills itself no one is going to cut you a check to repair your engine.
