    Hey guys I gotta pull my 324 out of my 55' super 88 and I am toying with the idea of doing a big valve conversion etc. to the heads. I want to know if any of you have done this and what are the power gains/advantages?

    Also what does this kind machining run($$$)? Thanks guys in advance.....

    I would go with 1956 heads and/or call Tony Ross.

    Yup I've heard of those coveted #10 heads.....but the ones I've come across have been $$$.
     
  4. Whatever you do, make sure you put hardened valves seats in the exhaust side.
    And by the time, it wouldn't cost much more to put the oversized valves in.

    I did it on my #8 heads, but have yet to see how it all turns out.

    Watch this -


    I do this a lot on Studebaker heads (have also done many of the Big Three also). Larger intake valves, hard exhaust seats. Some carefull porting goes a LONG way toward finishing the big valve addition.
    With a good intake manifold and cam, it's well worth the effort/money.
