A piston set like this covers a rebore that's gone .020 over, which is a common step when a cylinder bore has worn or been cleaned up before. The 7.4:1 ratio is worth checking against your existing pistons or head before you order, since compression ratio is one of those things that has to match what the rest of the engine is set up for.
We don't have more detail on this one beyond what's in the description, so if you're not sure this is the right oversize or ratio for your motor, call the shop and we'll confirm before you order.
