Thanks Chuck and Tony. My intent is not really for big power ,....though power is always nice. Mostly I wanted to improve on the oiling a bit, have more efficient chambers, and improve longitivity. The way I drive, like an old Grandmother, it should be my last build, as the engine that's in it has been going 20 years, still pretty good. Yes, I dressed it up a tad with valve covers, intake , aftermarket ignition. When I'm done, I'll still have the original engine , running, complete, in storage. Charlie, Ruben is the gold standard when it comes to cyl head work , for sure, his work is clean and precise, and he's sure been doing it long enough to know. I did all the engine assembly for Valley head Service for 13 years, worked along with Alex and Ruben, good guys.
