The cam should work well for smooth torque. It is a very mild cam. The stock carb or dual small Solexes with chokes should work. Balance the engine. You deck hieght should be .040-.060". Both ways work for increasing clearance. The block deck should be checked to make sure it is even on both axises. Don't take a lot off the case to prevent having to take some off the cylinders or using barrel shims. Flycutting the heads will allow for the proper compresion once you set the deck hieght. 6.5 to 7.50 to one compression. More and you may need race gas.
