Early Slant 6 Rebuild

Probably. That's actually what I'm counting on. Last compression test, it had 155-160 on all six so the top end is great. It doesn't smoke a lick. So the ring seal is good. With the new bearings, oil pump and timing set it should be golden. Remember when I keep saying I "might" leave it a slant? Yeah. That.
Don’t want to get the original post off track, but you may want to do valve seals if they are OE.
