First Generation Firebird-L Mailing List ......................................................................... I've done 2 Pontiac engines with the rope seal and they ran great without leaks. It's been a very long time since I did a rope seal, but as I recall, the key is cutting small amounts at a time in making it fit. Old Joe In a message dated 3/8/2009 9:48:42 P.M.

First Generation Firebird-L Mailing List .......................................................................... Hello, I have just got my engine back from the machinist and I purchased the viton seal and it DID not fit. After much discussion I ended using the graphite seal that came with the felpro kit. I believe that pontiac blocks do indeed different sized glove where the seal fits. Hope this helps.
