I just bought a pair off this heads and i was told that im going to have to notched the pistons on my car so they can fit,I have a 1991 gt with a ford racing short block,the one that comes with hyper pistons and a explorer cam,any help will do i also wanted to upgrade my cam,whats the biggest cam i can get
i have the performer rpms on my 93 302 block with a tfs stage 1 cam that, i just installed last week w/o any ptv issues w/ the 202 valves so you might want to clay the heads first b4 buying that tool.
yes it made a good difference, exhaust sounds crispy too, for the price i think is a great head next to the TFS T/W heads. I dont know what the biggest cam you could get would be but remember to clay the cylinder to make sure your ok.
