Hone the cylinders lightly, then measure the taper using a piston ring, assuming you don't have a dial bore gauge or an inside micrometer. Sending an engine to a machine shop is like asking a personal trainer if you need to exercise- - - - -you're going to get the full treatment. That's how they make their living. Rebore the cylinders- - - -new pistons- - - -regrind the crankshaft- - - -new cam and lifters- - - -rework the cylinder head- - - -pretty soon, your checkbook is going to need CPR!
