Springs, locks and valves for an additional $109.00 I know nobody really wants to sell them bare so that price is usually jacked up a bit but still....I doubt they are Manley or Ferreas.

Bryce's provides nice high quality Manley valvetrain with the Airwolfs. I believe he buys them raw and puts in his own hardened seats and guides so likely not apples to apples even if they are the same castings. You certainly don't want to skimp where it counts IMO. Edelbrock is selling lower grade heads now and they cut the costs in the quality of the seats and finish machining.

Casting quality of my pair of airwolfs looks to me to be on par with the eddies
