What if you go with something like a 305 cam and end up not hitting your goal? Going to put the 305 and go 306?
The only reason I advise against putting a bigger cam limited by stock heads is because you will have more usable power with a smaller grind. Larger cams diminish low-end power and move the power band much higher in the RPM range, beyond where the stock heads can support. 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.

JMHO!
