318 LA Rebuild Advice

Update:

Plastigauged the main and all connecting rod bearings:

Mains = all .002 marker
Connecting Rods = #1 was slightly a bit larger than .0015 but not .002, #2-8 were all .0015

Then measured main and connecting rod journals with a micrometer, making an X with instrument placement.

All looks good within the service manual limits

Connecting rods are all numbered #3418645
Pistons # 1266 with a 20 on the top of each piston
- So this means the pistons are all .020 large than STD bore of 3.910?
- Thus means that all my cylinder bores are already .030 over?
I do not have a bore dial gauge (yet), but did use my Starrett caliper and they all measure 99.62 mm (or within a .02" deviation) = 3.922"

Therefore would I be able to reuse these pistons with a "stock" rebuild kit or am I looking at oversize or a trip to a machine shop?
