Guys, Dennis sent me the info on the set of heads he has. They are off an 1835cc Great Plains motor that broke a crank. They are bored for dual spark plugs, and have a set of aluminum valve covers with them. He didn't say what list was on them, but priced them at $450. He also added that the fellow that had the motor said there was around $600 of machine work done on them. Don't know if they have been ???????ported, poliished, plug holes????????? Bobby
