I wouldn't and haven't built an engine without torque plates being used, but that's me. I understand Ernies point though, what IS good enough?

Why not have it hot-honed w/torque plates?

There is a whole lot more to ring seal than just the rings and walls so why not take advantage of the advancements in piston machining and get a set of good pistons and rings, about $4K.

Of course you better have the carb's idle circuit calibrated correctly before you put it on the engine. Otherwise, if it's rich you could damage the rings and the engine could need re-ringing before it leaves the garage.

Seriously though, considering the cost it's hard to justify not using torque plates.
