Murfman, there's a cam-grinder in georgia who can grind you a cam to do anything you want. his computer will do anything the big boy's can do. he used to work for Reed cams, but has gone into business for himself. he reground and rehardened a cam for the mercruiser engine in my Model A, for only $75. and i'm well pleased with it.
his name is steve demos. call him at his shop in Jefferson, Ga. ph 706-340-6914
you probably know that F-head 134 won't stay together at high RPM. you'll want a low-rpm, high torque set-up for dependability. look at those skinny rods...they ain't made for screaming!
