Aluminum heads

When I said .700 lift I was referring to what the head would be good for. I know I’ll never get that big of a cam. A lot of people on this site are in a league that I will never be able to get to. I work to much and more money than I have got. A set of these heads for me is a big deal. Now , should I put them in my little teener that I know very little about except that I bought it from a junkyard right after the truck it was in was totaled. The motor is a fresh rebuild except for thrashing it has got from me. Probly not. Will I ? Sure. it will give the younger crowd where I live some experience and a chance to play with something most of them will never afford.
