I bought head studs, rocker arms and a sealant kit from Henry, and believe he is a top notch builder, and he is qualified to put sealant on the case webs at the main bearing locations.
I also consoled with Peter Dawe, and had my case, and rotating assembly checked by the machinist he uses. All bearing clearances were checked with the case assembled dry, and I was told all NOT to put anything on the case halves at the main webs. He said if your an expert like Henry, fast, and do it perfectly you might only add a few tenths (.0001"). I am not that expert, and I will assemble the webs dry, just like the factory did. Just like any precision bolted assembly that gets measured dry. I hope to put this engine together one time.
Sealant on the webs can and does go wrong, leading to oil pressure problems.
