I have square port 454 heads casting number 14096188 and cant find valve seals anywhere. Everywhere show fel-pro ss71152 and that is for a single spring setup and mine has dual springs so the seals will not fit inside the inner spring.

I have called everywhere and they all show the same part # and its not the right one.

Any ideas??

rs,
WHat you need to do is measure the part of the valve guide where the seal is pressed on. Then call your machine shop ( a parts store will not have a clue ) and tell them what size the guide is and they can tell you which seal to use.

If your heads originally had single springs, and you are installing dual springs, you will have to get the guides machined to fit.

If your heads had dual springs on them and the seal is a rubber one with two steel bands, call me in the morning and I can tell you the part number, I have a box of them on the shelf. It would still be a good idea to measure the guide to be certain.
