Simsol, i had a read of your thread on slipped chain/bent valves.Looks good, you also dont have a lot of wear on your camlobes, so you may have gotten it in time, I was at your exact point then assembled the engine back together with new chains tensioners oil pump water pump etc and when we started her it was a no go as the chain must have slipped on the cog at intitail breakdown enough to cause my whole left bank to have bent valves.
My engine is a LEO and yours a LY7, LEO being lower power may have less interference valves/piston.
Secondly my right bank cam timing chain slipped at startup/idle, yours at higher revs.
After replacing my chains, i believe the cam chain slips at the idler gear. This would retard both intake and exhaust valves. Also why i had the strange delayed pop when doing compression checks.
I assume my cam chain slipped maybe 3 teeth or so, Simsol yours may of been much more as you were at higher revs.
In retrospect, if from now on any members here suspect slipped timing chains, a compression check would be a great next step.
Maybe do a compression check with chains on, then chains off to confirm if valves are bent.
