Alright so I just wanted to update this thread as to what the status is. Well I have motor ready to remove which will be this week. Both heads are off and problem found. The valves covers are in about 30 pieces as I had to break them off due to injector hold down bolts being stuck and heads all twisted off. That slowed me up and lowered motivation by about 90% so started working on it again this past week and as of now, the block is ready to lift out.
So The main issue with the motor is that the drivers side piston 3rd back, had left intake valve break off at the base of the stem where it meets valve body. Then it got hammered around inside the cylinder and cratered the head and likewise the piston. So this is why engine is coming out. Only 2 tiny scrapes in cylinder wall maybe 0.005" deep that should be fine as they are right at top of piston travel. Engine builder is a good buddy of mine so he thinks it should be OK with a hone but will decide once we get to that point. Not sure why the valve broke as I had a theory but doesn't appear to be what I was thinking. So can't dwell on why as it will get a new head anyway.
Needs a new head and am gonna swap in some lbz rods, delip my stock lly pistons and key stock crank and cam. Then new bearings and main studs and rebuild the heads and maybe do some porting since it is apart. Then paint and I'm gonna machine up some upper valve covers also. I am doing machine work for the pistons and keying. Can't swing for carillos or stuff so figure lbz rods should be just fine. Not that I wanted to do any of it in the first place but it is what it is.
