Well for anyone interested I decided not to port them or anything. Not because it cant be done but because I dont want to butcher up a good set of heads and I'm too lazy to take them off the motor. I can hardly sell them how they are now, let alone afterwards no one would want them.
Just gonna put my new cam in and hope for the best I guess.
