This is a bit of a head above the parapet job but what works for me and, so far, has never failed be it road or competition engine is:
Block to Crankcase: Threebond 1215. No gasket.
Sump to Crankcase: Silicone Gasket. No sealant.
Head to Block: Loctite Copper Silicone 5920/5980 with Head Gasket.
Exhaust Manifold to Block: Loctite Copper Silicone 5920/5980 with Manifold Gasket.
Crankcase Nose to Crankcase, Dynamo Tower to Crankcase: Loctite Black 5990 or Threebond 1215. No gaskets.
Tappet Chest Cover: Ditch the original tin and use a cast aluminium version or make one from 1/4" aluminium plate and use a sheet of Rubberised Cork Gasket.
All Studs to Crankcase and Block: Fix in with Loctite Stud Lock
