Ive done some searching but would like opinions. I have a 01 cobra motor that im rebuilding to be blown. Im having my heads cleaned up with a 5 angle valve job, new valves etc and i was going to gave them ported or for around the same price get a pair of stock 03/04 heads and have them cleaned up but i cant afford to port them. This is going to be my last build for a while hopefully. What would be the best decision n the long run?
