I have Cossie 272 cams and Buschur Racing springs and retainers. My question is will i have valve and piston clearance problems when i put in the new cams? Does anyone no what is the least amount of clearance you should have? Or what is the most clearance you should have? Thanks in advance for the help.

 

Has anyone who used these cams had an issue with valve/piston clearance.
