well i would start with factory and see if you like it since you know that is a safe place to start. after finding the factory settings I use a degree wheel and cam sprockets modified or made for making adjustments. if you go to webb cams you can see examples of those or megacycle cams. i put the crankshaft at tdc unless i am using a piston stop. so if i were you i would put the crankshaft at bdc, remove the cams, check the setting as you go and get the count you want to start with, which in my case would be the factory setting. then go from there. i you are thinking that chasing hp that way is a long path, you are right.
