What's available for 409?
That's what I do too. These don't squish apart like the thin cork.I use the cork 3/8 thick from Showcars. Glue them to the valve cover and grease the side that contacts the head.
I wonder why a company that makes a quality product, quits making them? Oh, yeah, they quit making money on it because it is such a good product - my bad!I pretty sure they are gone.
Yeah, they're the ones, who makes them for the Chevy BB and SB?I wish Fel-pro made those blue rubber ones with the steel core for the BB and SBC for the 409's. Them suckers do not leak.
