Bolt sizes

[Piper]

What are the bolt sizes from intake manifold to head, and carbs to intake for a 440?

The intake to head are 3/8 coarse, and the carbs used studs that were 5/16 coarse on the intake side and 5/16 fine on the carb side, so you will also need 5/16 fine thread nuts.

Thank you. we sell a bunch of this stuff at the branch makes it easy to just grab it off the shelf.
