And was wondering what are the best heads for lets say a 6.0 to 6.7 Forced induction and nitrous.
Would the same heads work on a stock short block 6.0 with a nice cam and a whipple on 10psi? This is most likely the motor that I will end up with for my truck. I just can't justify spending 10k on a motor.
I have 0 experience with heads. I am also planning on going to a major car show swap meet in Moultry Ga in November. I would love to pick up and engine and maybe some heads. I need to learn a bit more before hand.
