Commando heads

Which Commando's are they? The 177's or the 190's? The 190's took the place of the W-5's. They are some vary good heads. IMO. Thats a fair price with the roller rockers.
I'm not sure. The guy who has them is a friend of mine and is out playing GI Joe this week (Army reserves) I will look at them next weekend when he gets home.
