take measurements if it doesnt need machine work assemble and drive. All builds are a tear down and inspect now everyone here will spend your money but remember its 3 choices Overhaul, rebuild, or balance and blue print. balancing and blueprinting is expensive and should be considered for an all out race application. Overhaul is new parts and gaskets not much machine work, rebuild is the machine work etc. you have to measure and inspect decide which one you are doing. each one goes up in price naturally.
