Marty,
Get rid of those lousy K&B bearings if still in it. I ran K&B 82 in my cat for a couple years, still have it as museum piece, identical except bigger bore, give me a PM or call if you want more info. Keeley turbo head does help over original (too much volume). OEM tubular con rod is fragile too, check with Gary Preusse if he has any RPM rods left and Keeley turbo head. Just my $.02 worth.
