Z/D/H, LOL, good abr. The factory never did one.
I know a few machinest that do alot of work to the parts and make it all work with stock parts at a much higher level. But since they have the talent to work the machines and such...
Heavy block height milling, head milling, switching in pistons from different year engines.
I'll just stick with an aftermarket piston and a nice balance job.
