I have owned every casting number of 429-460 cast heads they made execpt for the PI heads and the ones without numbers on them. I just bought a parts truck that someone has put what looks to be an 80's model motor in. I would like some info on the heads without numbers on them like what years they were used,chamber size and valve size. The motor runs like it has a vacume leak and has a D8 intake on it. I am curious about a port mismatch and maybe it is sucking from the lifter valley.
Thanks for any info
