    I need a pair of these for show on my '70 GS455. I've seen them from several sources over the years and wonder which ones currently offered are most like the originals?

    Someone on here makes them & I believe also sells them on eBay. I've never seen them in person or compared to NOS but they're reasonably priced.

    Mark Reeves made the best. They were cut perfectly with sharp corners. Not like the crappy round looking ones everyone else sells. I had a set on my GSX and they popped back in place nice too! I don’t think anyone else is making his style anymore. Someone should find out who his manufacturer was!

    These are them. I would rate them as better than NOS. 74A9FE4E-6674-4E24-8ABE-1C371C63E973.jpeg

    The original outside textured coating was a medium gray, not black or dark gray. And, more importantly, the actual originals used a yellow-ish cream colored foam, not gray, like Pontiac & Olds seals.

    Here's a picture of an original set of foam seals from an unrestored original '70 Stage 1 engine:

    Something else that you'll notice about so many of the re-pops - other than the foam and outside coating being wrong, is the wrong shape of the rear corners of the re-pops compared to the originals. Look at the pics of the originals and see how the rear corners of both the right and left seals are actual near 90 degree angles .... or at least an extremely tight radius, not a gentle curve like the front of the original foam seals. I see so many of the re-pops with a total mish-mash of combinations of gentle corners and hard corners, etc. Seems to me, just Google an original verified pic. If you can produce them in the wrong colored foam, I think you could produce them in the correct colored foam ...

    This is an NOS set for a big block I got here on the board a few years ago.

    Looks like they were bought early in 1973, according to the handwriting on the package of one of them.
