Heads

How large of valves are in the heads? And how large are the runners? (in cc's) What camshaft are you running? Also what intake and carb?
Small engines are easily over cammed and carbed unless your racing them, the same applies to the heads. Every engine combo or instance needs a given set of heads to work to its fullest potential. Not every engine needs or wants a set of 360's, magnums' or eddy's. When building a engine choose parts and pieces that will work where you'll be driving most of the time and in the rpm range desired. This go's for everything in the engine from pistons to the intake and cam, carb, and ignition, type of crank and rods, etc. etc. If you need questions answered or just some clairity of direction then give me a call.
