    thanks ben, I take it that they are just standard heads. This guy want to sell them to me claiming them as high performance heads. he wants 250 for the pair what do you think? are they 64cc heads?

    Dont buy them, those valves are really tiny, you can fit up to 2.08 intake on a 350.

    I cant believe the guy wants $250 for them /forums/images/graemlins/eek.gif
    $50 maybe. I bought a set of 186 (64cc) camel humps with ported exhaust for $50 then cost me another $150 to rebuild. Most performance GM castings can be found for around $200. I have a decent list of GM performance castings if you like it /forums/images/graemlins/thumb.gif

    Thanks for the info I knew something just was not right about those heads. I would love to get my hands on that list you have.
