Machine shop 440 Mopar questions?

Possibly they

Concerning pistons, cast, hypers, forged will all have different clearance requirements. I know one can assume that the piston mfg made the pistons to a nominal size, but I would rather not be guessing on something as critical as piston clearances.
Wonder what kind of finish the MS put on the cylinder bores. It is different depending upon moly vs chrome rings.
The same thing goes for the head deck finish. A multilayered gasket wants a different finish than a composite gasket does.
If the customer does not specify what he wants a good machine shop would ask.

I agree 100%. The piston should have the clearance built into it. If it comes out the box at nominal size I’d send them back.

I also agree that surface finish and such should have been discussed but the shop should be asking the questions. If they aren’t asking about the gaskets and the rings you are using then that’s a hint you may want to find another shop. That is the responsibility of the shop to know what finished and clearances to use and to educate the customer. Anything less than that and you start looking for a different shop.
