318 LA rebuild after losing a valve seat

Yeah, don't use that stuff IMHO! Some fresh motor oil will do. Same on the pistons and rings. Read up on how to prime the engine's oiling system once assembled. It's a VERY good thing to do.

Yes, and you could have some re-manufactured rods there. Anything is possible. The order of the rods is not really important as far as I have ever known. The direction of the rods bearing tang notches (relative to each other and to the block) and oil squirt holes IS important.

Mixing up unmakred rod caps to rods is not hard to do. As pt70 sez, they cannot be mixed.... at all. Next time you take apart an engine, if a rod is not marked, then mark it yourself. HF has some cheap number stamp sets.... which I assume will not dull with the fist use LOL.
