You need to check piston to valve clearance if you change the cam.

I would choose the 274 R if I was to pick one.
Yeah I forgot to mention valve train interference problems that you may run into such as: valve to piston, rocker arm to stud and spring binding. Leave that big ****** alone and let her eat! Measured on a dyno that was probably at the rear wheels, 537hp is real good. That means it could be making as much a six hundred at the flywheel. Not bad not bad at all! Post some pics if you can!
