Didn't tear anything down yet. Only removed the valve covers during testing. It still runs. Idles just fine but put a load on it and sounds like crap. Once I swap in the new engine I'll try and find the root cause. My best guess is head gasket. Or cracked valve seat. One of the heads for sure had a previous crack repair.

Still waiting for heads and cam/lifters to get shipped. Maybe this week. Not holding my breath though. I think the rod and main bearings were supposed to get delivered today so Mike can assemble the short block, minus the cam of course.
