A piston set like this is meant for a rebore job where the cylinder has already been taken out to the .080 oversize to clean up wear or damage. The 8:1 compression ratio noted here matters for matching against the cylinder head and combustion chamber shape you're running, so check what your engine was set up for before ordering.
Our records on this one are thin beyond what's on the box, so if you have questions about pin sizing, ring pack, or anything else not stated here, give the shop a call before you buy so we can confirm what you're getting matches your rebuild.
