		All the oiling mods you mentioned are very helpful.  Another area that needs attention is the oil passage where the oil pump bolts on.  You can lay the gasket on a see how small the hole is in relation to the hole in the oil pump.  This hole needs to be drilled out with a 1/2" bit and radiused with a grinder.  As for the restriction in the heads, I tap the hole and use a 1/8"npt pipe plug and drill it out with a 1/16" drill bit.  I'm always afraid that I'd accidently drop a jet into the engine during the build.  Sodium filled valves were used in HR and MR engines.  I've got a piston with a sodium filled exhuast valve head sticking out of it on my shelf that came out of a MR in 1972. Rusty  |
