What is wrong with the new afr competetion head and how do u fix it
As far as the heads i have now...i have a story aboout these heads and why i am getting rid of them....last spring i took the victor jr heads in to get ported and the did so...he was way over his estimate but anyways...he phoned me and told me they were flowing 301 cfm @.700 after his porting verus 285 out of the box.....2 days later he phoned me and told me he found a problem with the heads as the valves r pretruding 27 thou out of the heads.....i asked him that is normal and he said no so he told me he would sink them 25 thou........after paying him i asked him for the flow sheet and he gave it to me the flow number was 259 @700 now and he sunk the valves 50 thou......he argued he did the right thing.....anyways to get the flow back i got a guy to install 2.10 intake valves from the 2.08....he told me they flow 298 @700 now.....but he never sent me a flow sheet i have to go by his word.....so i figured i have enough of these bastarded heads and figuring the afr heads were the way to go.........i figure the heads r restricting me......it is going to cost me money but i am not happy the way it is right now the car should run around 10 flat not 10.20s or 10.30s...........that is why i figure 3 tenths is reasonable............thanks and i would like to hear your comment now u know a little more about my situation
