Is there such a thing....
...as a decent 4bbl gasket available these days?
I got a 4-hole 1/2" phenolic 4150 spacer from Holley. The why of that is not pertinent. It came blister-packed on a Holley card with two gaskets. They seem hard and thin to me. Not that this tests anything, but putting the two of them together and squeezing everywhere I can with fingers, I can practically breathe between the two. I'd think they would do better than that. Not exactly a flange width sealing test. :)
I am not a fan of using sealant on fuel gaskets , but I am considering using a very light smear (wipe with a finger) of RTV, or maybe some 3M adhesive (used for body trim attachment) with these gaskets. I might hit the gaskets with a bit of sandpaper, too. There is no 'finish' to 'em. They are just grey gasket stuff.
That they came in a Holley package maybe means they are better than other available junk?
I don't mess with this car much. The carb has been in place since build...probably 15 years. I remember better gaskets commonly available 'way back then'. I am not trying to solve any leak/vacuum/performance problem. Also not looking for some .200" thick gasket meant to address warped stuff. I AM looking for a GOOD 4150 4-hole gasket.
Any points of view having to do with new gaskets and simply bolting on a 4150 would be appreciated.
Thanks, folks!
