Champion rockers on a 440cc


Well-Known Member
Has anyone put champion shaft mounted rockers on a gx390 or other big block clones? I have tried putting them on a 420 and a 440 and they are on such an angle that the adjustment screw is down to the last few threads before it makes contact with the valve stem... it's like they are too high off the head.. I don't see anyway how this can be correct and yet they are made for these engines.
