How's everybody doing? With a nice day up here in New England and finishing work early, I decided to take some time and clean up the pistons and block in preparation for replacing the seeping head gasket. I finished but am left a little confused. I found 4 pistons marked "A" and 2 marked "B". Any difference?

Thanks, Steve
 
Hello Steve,

there is a minor difference in diameter, those are grading marks, so I think your engine must be original un-rebuilt?, at least as far as the cylinders.
