is this a rebuild for a motor? if thats the case then you have too pull motor and take it all appart. head , pistons, drank and in and ex manifolds and everything thats electrical then you take it doun to a machine shop and they will do the rest depending on what you want. if you go turbo at this point it might be a good idea to buy different pistons from JE or some other company or even go to the turbo GTE pistons. buy a new oil pump while your at it and have the crank ground with new bearings everywhere, and get a head job and to finish off balance everything. pick a good machine shop somewhere with a good history and dont be suprised if you have to wait a month and a half for them to finish the job. well have fun
