Do your pistons have a number on top? If not they are standard, if they have +1 or 20 they are first bore oversize. If they have +2 or 40 they are second bore oversize.

Thank you!
I will have to clean the pistons up a bit before i can see any numbers! They are pretty bad!

before you buy pistons rings measure the cylinder bores to make sure they aren't oval or tapered, and check the pistons to cylinder clearance. if they are out of spec you will need to overbore.
