What I'd give to have that body style. I was close 2002, should have. Cant find them now. I hear you on the stuff your friend told you there's a lot of different things for different heads some techniques you would use on a small block Chevy exhaust don't work on a sb Mopar for instance. I dont know everything, sometimes I mix up. I'll 'never' quit trying to learn something and if/when I find out diff.. I try to figure what was the differentiating factor, the culprit. Some things might not work because we did something wrong further down the tract, the turn, or the bowl, or throat cut. That's what keeps it interesting! Lol
