The best thing to do is find a good machine shop take your hardware to them tell them what you want and dont want if he's
any good he will talk everything over with you. first off you will need all the rods, pistons, pins, crank, and all bearings. this will
insure a good fit for your parts also a good machine shop will take in consideration of the oil that will be on the bearings just like when your balancing a crank and rods. The only need to go zero deck is to gain comp. and you are also getting very little amount of torque with it as well. also you pistons shoud match you heads so you get a good better burn.
