ok so i need help figuring out what blew my motor. im posting some pics of the heads first. My first question is does it look like the piston was hitting the intake valve. I had a new cam installed and had the heads off last year and I do not recall the line on all the intake valves. Any input will help. They are AFR 165cc on 306. Cam specs Im not sure but will post asap. http://gallery.me.com/shaned1979#100135
