A smaller cam will provide the same gains in the upper RPMs approaching stock head limitation without sacrificing the bottom end. I ran the XE 236/242 for awhile with full bolt-ons and trapped 108mph. Guys with much smaller cams are trapping 110+. Drivability wasn't an issue with that particular cam, but the performance wasn't what I had expected (5 years ago).
But if the OP is planning on doing heads in the future and isn't too concerned with overall performance right now, running a larger cam on stock heads won't hurt anything.

i agree, a large cam bring choked off where its supposed to make power isnt going to produce results. the motor is currently apart, im still not seeing the point in rushing it together while the heads are off just to do a cam only build. again, if money is an issue thats one thing but if its not then this just seems like beating your head against a wall.
btw Joe, i trapped 110 with only bolt ons
