What valve seals for 1990 454 mag engine????

I am replacing valve springs and want to replace the valve seals, do I use the 3/8 .700 rubber caps? Thanks!

We always cut the guides for a .530 PC seal. Any local machine shop can do that for not that much money. They are far better then the umbrella seals.

I bought a seal stem cutter from summit because I had so many heads to do and the umbrellas suck.
