More on teh busted engine... tonight, I did a leakdown test -
15/10/15/20%
There was some coming out of the oil drain holes back up through the head, but almost all the leakdown was coming out of the exhaust - I could hear it rushing out the header pipes as well.
So, looks like I will leave the bottom end alone and rebuild the head for now, since the rings dont seem to be the source of the blowby.
Pulled the head off the spare engine, a little dirty but it appears it was in pretty good shape
