Well, starting to order all the O-rings, gaskets and extra shenanigans that I will need to assemble the short block... I can find pretty much everything on All Season , Merchants site and Henry's.
The machine shop that is resurfacing my heads and doing a complete valve job disassembled my oil cooler assembly to clean and hot tank it, I cannot find this O-ring that seals those two half's.... any ideas on where to look? I thought I read while back that GM doesn't sell that O-ring and you gotta buy a new cooler, but not really sure..
