Rick, Thanks for the heads-up on 3/8" reach in Aluminum. I checked the specifications of the plugs via the link that Russ posted, as I was hoping to find
another shorty option for my iron heads. But these are 3/4" thread length.

Do you have a part number for 5/8" hex x 3/8" thread length, 14mm thread, gasket seat/seal, in a variety of suitable heat ranges?

Thanks, Arthur
