If i was to install a percision cam in my comand for lawn mower racing, I understand it will require longer valves, solid lifters, adjustable push rods(preferably cut to length solids), adjustable rocker stud kit, and stronger valve springs. Please correct me if I am wrong. Am I missing anything else that should be done at the same time?
I am not understanding the longer valves. If the cam creates more lift, wouldn't a longer valve create a bigger valve to piston clearance issue, or is that the reason for the adjustable push rods?
This is a CV22s that I am building for mild power for now. It will get some head work done as well. Eventually the rods, pistons, and flywheel will get done. Looking to start with the most bang for the buck.
Can anyone tell me how much can be milled off the heads without getting into clearance and parts breaking issues.
Thanks, Rob
