primary case...grease both sides
timing case....dry..used one to get a tad more clearance for 4 valve pump
oil pump.... wet with oil at assy
oil junction block...wet with oil
alternator cover...ThreeBond, Permatex, etc to cover side
rocker boxes...dry...use the good sandwich gaskets, you'll probably be able to reuse them with a little care
copper washers...fully anneal and flat sand
inspection caps...soak in oil and good luck...I'm making up some copper for those, will post results...I think Webby has got his to not leak.
ThreeBond seems fairly easy to clean up with a bit of B-12 or acetone. Except for the drive sprocket, I won't use silicone.
I'm with Buckshot on this one, I used "Wellseal" (a non drying type sealant) for the case joint. For everything else get good quality gaskets and smear them with high temp grease, that includes the head gasket.
The only places I have RTV type sealant is a light smear on the gearbox output shaft to stop gearbox oil from leaking down the splines.
As for the rocker covers, I've installed 'O' rings everywhere, they work well for the large tappet access holes but the smaller ones on the side would still weep a little oil so there's a little RTV in there too, it also stops them from vibrating loose.
