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.....
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. Mike
Thanks guys for your input and information. Mike those guys, machinist, are about 2 hrs north of me...hmmm maybe ill be taking a lil road trip in the future with my #8's.. Posted using the Full Custom H.A.M.B. App!
