If I go 416 with 11 to 1 Je piston would you put a rod in it? Anyways. If I buy heavy valve springs and hard faced rockers and 1mm oversized valves , does there size have to match whatever came i choose to put in? for example a web our a sparks our whatever? Our should I just buy a drop incam and for get it ?

th ehead will have to match the oversized valves. some cams and valves go together. if you get areally wild cam alot of the time you have to run shorter valve guides and such. who ever is doing your headwork should have agood idea of what is needed. talk to scott at profabatv.com

ALSO, you do not need a rod.

I waould also suggest going to alarger carb with larger vlaves. you may not even need to go with a larger valves for your current set up
