Valve Seals

We offer valve seals in both stock replacement types and aftermarket Teflon or "PC" type seals. We also stock a large assortment of bronze valve guides, liners and hardened seats for cylinder head rebuilding. Give us a call for details.

We also sell replacement parts for rebuilding heads. We now carry:
500 OD bronze guides (set of 16): $39.95
Exhaust Hard (Stellite) Seat Inserts for 1.74 valve size (set of 8): $49.95

These are our stock replacement type seals, but they are a much improved design over the factory type "umbrella" seals. These actually fit positively over the valve guide and "wipe" the valve stems as they open and close. Made from a polyacrylate material, they are much less susceptible to heat and will last much longer then the original rubber type seals. Sold in sets of 16. Use one set per engine. No machining or modifications of any type required. Use with single or single with damper type springs only (not for use with dual or triple valve springs.)

Part No: 101-1050 - Polyacrylate Valve Seals - Set of 16 - NEW - Price: $8.95

These are our aftermarket ALL TEFLON type seals, sometimes known as "PC" seals for Perfect Circle, one of the first companies to start selling them. These actually fit positively over the valve guide and "wipe" the valve stems as they open and close. Because of the smaller outer diameter of these seals, they are the best choice for use with high performance dual and triple valve springs, however they require the outside of the valve guide to be machined down to either .500 or .530 (depending on which version of the seal used.) Stock type valves will use 3/8" stem size, while some aftermarket heads will use 11/32" (slightly smaller) stem size to conserve weight. Sold in sets of 16. Use one set per engine.
