Those cylinder head pics are from pretty early in your diagnosis, not presently, correct?
The timeline of this is VERY long and confusing to follow without researching this book!
Who pulled/installed the heads?
What was checked and by whom?
I highly agree, looks like it's on a high petro diet.Valve seats are likely just as laden with deposits at that time.
_Currently
Where was the intake vacuum leak, at which cylinder, pairs, and /or multiple locations?
The discovery and introduction of new base engine problems in the build/rebuild heavily taint this deal, beginning with the original, previously undisclosed, original dyno failure when trying to diagnose the noise.
Bottom line, the engine lost oil pressure on the dyno at birth... from an assembly failure. It just seems to be patch jobs from that point.
I'm deeply disappointed in this deal.
I've been on Paul/Jeff's end.It not a easy pill to swallow,
Menn take responsibility for their mistakes, and good business men make things right.
With that I'm impressed with Jeff's current appropriate actions.
The rest of this deal is a train wreck.
With that, I think I'll just watch from the sidelines from here out.
