What paint would be good for covering the lifter valley for aiding oil drain-back? What high-temp paint would be good for painting the block? Is there something available in spray cans?

I've heard the POR 15 engine painting kit is a good one!
Yeah, I have a new container of POR15 Chevy Orange sitting here. Is that stuff resistant to oil (could paint intake valley with it too)???

That Glyptal idea was first published in "How to Hotrod Small Block Chevy's" back
in the seventies. It's hung around ever since. You don't need to go to all that trouble. Just deburr the valley with a "tootsie roll". It will work just as good without the risk of any paint coming off. Pay attention to the drain back holes.
This is something that really should have been done before machining and cleaning the block.

Vizard's book shows how to detail the oil return holes. Should I go ahead and do that and try to re-clean the block, or should I just leave it go now?

I say no paint inside. just another thing to worry about coming loose. If your cam bearings are removed I say go for grinding and realy get in and under those oil returns in the rear. Make sure all left over flash and casting sand is gone. If you have cam bearings installed already leave the grinder in your tool box

It is sorta old school to paint the lifter valleys it has to be super clear or you risk big strips of paint going off and pluging a lifter gallery or pump pickup....BUT there are places that still do it...PAW for one uses Rustolum on the inside of the motors they do...:)

I was sort of thinking out loud in this thread. After researching this some more and seeing your replies, I'm not going to paint the lifter valley. I'm gonna call the machine shop this morning and see if the cam bearings are in yet. If not, I'll just have them do the grinding for the oil return paths since the block is there. Shouldn't cost much at all.

Smokey Yunick in his "Power Secrets" books says to paint the piston tops with VHT high temp flat white.. Ive never done it but Im sure it would have a short term effect till it went away out the exhaust valve. :D

There are some high tech coatings out there for piston sidewalls and tops that are very effective. Probably overkill for this application not, to mention the costs involved.

Coating pistons, valve springs, etc. is fairly common these days. Some coatings absorb oil, some repel, etc...just depends on what component is used for. It's not that expensive to do but their seems to be questionable paybacks for the average user.
