I'm still running my original (119,000+ miles) as long as I can blow through it without restriction, I'm happy. I've never cleaned it that I can recall.

So, does the flame arrestor have a one way valve inside to prevent possible backfire flame from entering inside the valve cover?

No. It's free flowing both directions. It appears to have metal "louvers" (probably a series of them) which apparently block a backfire from entering the valve cover. It's visible from the valve cover end. I've never looked at one from the carb end. Some other Chevys (Corvettes, etc.) used a screen-like dome filled with a metal mesh which I believe was inside the air cleaner.

This is what it looks like at the valve cover end.

Here's some basic patent info. Not much use though.
