I been looking for a steel replacement cam for my HS50 and OHH60 but havent had any success in finding any other than new and they are in the $50 and up range so I was considering getting a cam from Batman along with valve springs... I was just curious if anyone has used any of his cams and how they performed?? I was also thinking about a billet rod but according to his website and stats on the engine parts he claims the stock rod is good up to 6500 rpms which is more then I plan on running..
