Head question
I have a set of LS1 heads that came off of my Vette that a friend of mine said I should put them on my 07 Silverado 5.3 along with a LS6 cam and of course change out the springs as well and mill them .30 Would it be worth it? I know that the LS1 has a bigger chamber, but milling them should make it up.
