I saw a deal on some unused Procomp bb heads (the Victor clones) with 2.20" and 1.81" valves for less than I see the bare heads alone. I haven't bought them, and most likely WON'T, but was curious if the Procomp valves they include are even reasonable parts to use.

Never seen their stuff up close and can only guess at what they might supply. If they're junk, the heads aren't really priced any better since the hardware would just go into the dumpster.
