All Teflon Valve Seals - 11/32 stem / .530 OD guide

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. These are an UPGRADED type seal which will fit our Stealth heads. They also feature a smaller diameter which is necessary when running dual valve springs. Sold as a set of 16 pieces, enough for one complete engine.
