I bought these heads for my son, then was going to put them on a 400 I plan on putting in my 79 p/u..but need the money rather than wait until I am ready for them late next year.
Couldn't find the spec sheet but my son will be home tomorrow and I can get more info from him. They are 76 CC, magnafluxed, 2.02 and 1.94 stainless valves, new seats and seals, and I think they were milled .010. One has the steam port holes the other does not, I understand that they can be drilled with little problem, also know of people who say you can put them on a 350, I don't know.
I bought these on ebay, had delivery problems, bought another set locally for my son and then these came in giving me the extras. Because I wanted to make sure they are OK, I paid a local mechanic that I trust implicitly to break them down and check them out to make sure I didn't stiff anyone...he says they are good to go so my reputation is riding on his and he has a good one!
I am asking $399 for both shipped to your door in the continental US.
casting number is 333882 on both, although one looks more like 888882, any other numbers you want I can get tomorrow. thanks
