Could still be valvetrain from more than one source..

I've been listening to the old tick I had before (the one that was a valve spring in the end) on the YouTube video. That tick was slower and a little lower pitched. This one does sound quite similar but a faster cadence. So I guess I can't rule out a bottom end source. But I just kinda don't think so.

The only difference on the bottom end this time is Jay's piston replacing my blown up one and the sleeve (which doesn't seem to be leaking). I did notice Jay's piston pin was stiffer than mine. My other seven are totally free. Jay's has a bit of stiffness to it. But it's not bad. Otherwise his rod and piston look like my other seven. Same pin height, same bore. I replaced all the rings and bearings..

Yeah, 15-30 I'm guessing is too thin, and can be contributing. Wouldn't hurt to try a 20-50, see if you have an improvement. Probably would be running at least a 15-40 if it were me, though don't recall you bearing clearances. That would also help in the event you do have sloppy pin clearances too.

Guessing you've checked the fuel pump eccentric too, and the pump itself? Close inspection of the distributor?
