Gerard,
Certainly looks cool, and accepting the "I-know-its-there," and "all-contaminents-removed" and best of all, the "better-oil-return-flow," what about the painting sequence? You mentioned hand cleaning and hand painting. Your pictures looks like you you painted before bore. What about cam follower bores, cam bearing bores, distributor drive bore, oil pump bore, thrust washer face, threads, etc.? What about crank/rod paint? I can imagine just plain good detail hand painting, or honing, tapping. What about paint viscosity, thickness when dry? If it doesn't matter, great. If it does matter, would like to know. Looks like valve springs were painted. Does spring flex matter? Thanks for your expertise. Blueghost.
