I've always used Vitons with my cylinder head rebuilds. No problems in two years so far. That's over 30+ sets.

Felpro oem replacements. I had a head rebuilt with vitons they let way to much oil past. I replaced with felpro and problem solved.

Head was modified with bronze valve guides from MMR. I used felpro valve seals from the upper gasket kit and it started leaking after 1000 miles. Now I replaced them with mmr valve seals.
