Another episode of " Name This Part "

Top plates are 4 bolt Hooker header flanges to weld the tubes onto when making headers. You need the adapters for Hooker headers to use them . Once the headers are made you cut them apart

The bottom plates are W2 Hedman header adapters plates that bolt on the head and then your headers bolt to them.

I would be interested in them if the price is right to make patterns out of stainless
