Chevys had some soft chrome plating on the valve stems. It's the same way with king pins sometimes the bushings don't wear just the pins.

 I'd say a good racing fw has a SFI rating.

I thought catch cans were for direct injected engines. I don't think it should be vented. Does the engine have lots of blow-by? I know you were fighting a smoking issue.

The problem with all of this is that anybody younger than 40 doesn't see this as a problem.  They all grew up with technology and very limited personal freedoms and civil liberties that you and I enjoyed. I sold a car over the weekend and while cleaning it out I came across a match book (remember those?) that said on the cover "at least you can still smoke in your car".

Nicest I've seen is polished concrete. There are companies that will grind and polish your concrete that looks almost like marble. When I asked what it cost, the only reply I got was "expensive".

What I would do is the next time you pull up to a stop sign and it is idling fast, I would lift the hood and start wiggling at the carb linkage and secondary linkage and maybe give the vac adv. and pcv valve a sharp rap with the blunt end of a screwdriver to see what happens.
