just thought i would let you guys know that i got my new heads put on. I gained 80 more horsepower to it and now i hit about 4500 rpm and the fuel pump can keep up and it starts running to rich. and to add more bad news i was driving it home and the heads started to leak and started smoking so i had to take it back so he can reseal the heads.. once i get the new fuel pump on and everything running and tuned up right i should be putting about 350-400 hp to the back wheels

 

If the fuel pump can't keep up, I find it hard to understand how the engine manages to run rich, or gain 80 HP.
