Head Id.

Eric, those are excellent heads for a 360. I've been running a set on my 360 for the past several years and they work great. You might want to measure the valve size, and also check to see if they have the rotators on the exhaust valves. If so, remove the rotators when you do the head work. Mine have the small valves, but for low end flow velocity on the street, I prefer those over the 2.02's.
