Quick doublecheck guys, thanks

I've just started to assemble the motor for my SC powered project. This is the first time I'm doing the actual assembling of the short block myself. I'm just wanting to know what you guys think...

Background...
Ground and re-heattreated crank, .010 undersize.
Linebored and line-honed block, standard size.
Clevite77 #MS-1782 P-.25MM main bearings
ARP main studs (Pinto head studs)

Used plastigauge (green) to check main clearances.
#1, #2, #3 : .0012 - .0013 all were very-very close.
#4 : .0016 - .0018

The machine shop said for a boosted application I should shoot for the high end of the factory tolerance. He is well respected in this area and I trust him, but he does mostly V8s and alot of boat engines.

On the other hand, If the SCs oil pump is marginal, tighter tolerances would give better oil pressure, right? Sound like a little bit of a Catch 22. As it stands, I'm pretty much right in the middle of Fords tolerance range.

What do you think? It all seems good to me, I guess I just want a bit confirmation from those that have gone before me. Not looking for huge power, but I am planning to spin it to 6000 RPM or so.

Thanks,
Jess
