I wouldn't worry about it, these engines are built to last, the tranny is the weak link... mine has 151k on the bottom end and going strong. How many miles are on your motor?

Plus if you're gonna do that, it would require machine shop work on the cylinder walls (honing at the bare minimum, boring if there are gouges in the cylinder walls)

I was going to do piston rings and rod bearings when I had the motor out, but I took my heads off and the cylinder walls were PERFECT. You'll just have to see what they look like once you get the heads off.
