Default Be very carefull

If you don't have alot of experiance porting I would take them to someone that knows what they are doing and that way if they screw them up they can pay for em. If you want to improve them yourself if I were you I would just match port them to the intake and polish the runners. I did this in collage on a set of 906 for a 383 and it helpped.

Hold on...
Go get the head and flip it chamber up..
See the way the intake valve has that ridge that forms the seat...now lay a straight edge across it and see how much you can cut before you hit that hump.

You need to do the math and calculate your compression ratio to see if they're going to work on your motor.

You may end up with lower compression and alot of work for less power...do the math first
