What are the head gaskets made of on these motors?? Steel shim or composite??
Composite Gaskets, with an '86 Model, it's got some decent gaskets from the factory, no realy worries here. Sounds like the engine will be just fine to me.

The only reason I'm reluctant to mess with the cam plug on an assembled engine is because the rear cam plug is what sets the camshaft end play. A trick I think will get you by should you decide to remove the plug (that will be fun with the cam inside) will be to get the new plug and tweak it a bit. That is, this plug is the same as a Big Block gasser, but, the way the plug is made it is bulged inward into the engine. So, take a flat surface and level it out first (no more bulge), then install this plug in the block the same depth as the original plug, shouldn't trap the cam this way. Be sure to use a good sealant for assembly though, like an Anerobic sealant, or the Brown "Aircraft" sealant, don't use regular RTV.

The rear main seal is a snap, the rope seal will come out in one piece and there will be little-to-no residue left behind. Just wash out the bore a little with some brake cleaner and blow it out with shop air and you're set to install the new seal and then the cap. Pay special attention to the instructions that come with the seal.

No problems here as well. There will be some air in the system from the engine swap, etc. As long as you take care to keep contaminants out of the fuel system during the swap (post fuel filter) then you shouldn't have trouble. If you do, then a simple pump replacement or injector renewal will be in order, which can be done simply in chassis. With 30k, the injectors will be perfect, the pump should work fine too.
To answer one of the questions that Robyn presented...
Early or Later 6.2? In 85 GM updated the rocker arm/assemblies to a stamped-steel type, so your 86 will have these inside already. The previous assembles were condemed because of a few breakages, Mainly in early 82 models, primarily due to the clips around the anchors to the heads (full "0" verses a "C").
