OK....
The block is an original cast iron V block.
I took all my stuff about a year and a half ago to the our guys in Lawrenceburg, Tennesse that I know have an exceptional amount of Pontiac knowledge.
All 16 lifter bores were bushed with new bronze sleeves. I just need to look down into them to check out for the oil restrictors and whether or not they're out of round and if bores have a taper.
Knowing who these guys are I had a lot of trust in them....and by the way I still do!!!
I will check out a couple of different ways to deal with this and the last resort would be to have a discussion with them on how best WE can resolve this since this is a finished, unrun, off the pallet short block build with no time on it, still on the engine cradle it was delivered with.
