So I just completed a complete rebuild of my '75 SOHC. New pistons .050" over, good quality gaskets, Viton valve seals, stock cam. Head was professionally rebuilt and a reputable machine shop did the boring. Has 22psi oil pressure while cranking. I decided to compression test it just to be sure. I have 130-130-130-135 across the cylinders. Kinda disappointed when I see guys on YouTube testing junkyard motors with 175+. Anyone have any thoughts? Thanks!
