Eddy's will bolt down, and they come loaded with valves, etc. HOWEVER, you must notch the cylinders for valve clearance. If you went the Eddy head route, get the closed chamber, keep the chamber sorta on the small side, so you don't loose too much compression. Though you really need to know what pistons you have in the motor; hey it could be a Commando, God only knows and he ain't sayin.
