yeah i agree with you on that. i did use a wire wheel on the bench grinder to really clean up the valves, and a wire wheel on the dye grinder to clean up the valve seats on the head. other than that it was fine. i might take them apart at some point to port them before i do the rebuild but im having a hard time on finding info on how to do that. i have the tools, just wanna make sure I do it right. Any tips?
