I searched eBay, Summit, Jegs, Northern Auto Parts, and the like for the best price. At the time I bought mine, a seller on eBay was the cheapest. $81.95 with free shipping.
Russ, who makes those valves? EngineTech, SBI, Elgin, DYNAGEAR/MANLEY? I'm not sure which ones I got from Justins buddy. I'll find out today when I get my heads back.

most of those companies are buying from SBI. I get mine elsewhere , they are also stainless with stellite, and they have their own factory.
