All great info! I am starting a 401 rebuild myself. I saw the adjustable oil relief spring idea elsewhere. Maybe here. I read somewhere the idea of painting the valley with a product called Glyptol. Any thoughts on that?

Personally I do not like the idea of coating anything inside of an engine.

I have seen lifter valley painted but im with boris not a fan possibility of it flaking always crosses my mind but one thing that can be done is to smooth the vally to promote drain back

My 327 came with the Red Glyptol from the factory with no signs of flaking or chipping.
I used to collect trophies, more fun to collect gas receipts and put on miles.

Glyptol and other types of coatings have been used for many years both on and off the track. Even AMC used it on "factory" engines in the Rambler days. It is like any other product that someone might use. Done it right all is fine. Screw up and you pay the price. Don't blame the product, blame whomever did not follow the proper procedures, instructions, or recommendations.

cam bearing oil holes are huge in this motor bleed off a lot that can starve other areas and you can put a restrictor in line to the lifter bores if needed without bushing the bores cam bearings can be reclocked upon installation and re drilled smaller like .070 I like to do this instead of running internal line or restricted pushrods   I've never run an internal line actually is make sure you're crank is drilled right and that supply to rear main is drilled and put that little nut on the oil pickup to space away from pan   Some other brand engines have little plastic button on oil pickup but not amcs. 6 quarts

Bleed off is a function of clearance not the size of the feed hole.

... maybe some years don't, but the few I've taken apart do have a plastic button.
