LA 360 - Metal PCV valve part number?

[GoodysGotaCuda]

The plastic PCV valve on my Warlock has a terrible squeaking sound at high vacuum. If I pull it from the valve cover while running, the check back is visibly resonating.

I replaced the previous PCV valve about 2 months ago and the new one is doing the same thing. I have replaced the line to the back of the carb, no improvement.

Is there a metal version for the stock grommet that I can try?

Thanks

If you look at Rockauto plenty under pre-70 smallblocks  that should work but I really don't know
