i guess i will just have to wait and see when i open it up. I have never done this type of checks on an engine, but i feel that i could if i had a good shop manual for reference of torque specs and assembly notes. If i decided to re-ring the engine and the bores were in good shape, how much more work would it be to change the pistons to some KB's for a comp increase? again i have never have done this before so i dont know what is required for the install . thanks
