ok i got a set of gt 40 heads and tfs1 cam to put in my car i was just wondering if any one has done a home port job on heads before and what you used and any tips and if it matters if the runners have the same flow from cylinder to cylinder because i have no way to measure if they are the same. Also if is should gasket match or just smooth them out. I have ported a go kart motor when i was like 13 and looked good but i know that it is a different animal so i kind of know what i am doing but dont want to mess up my heads thanks for the help
