Need header ID help..

OK, a little bit of searching led to Casler being known for cheater slick type of tires in CA, but purchased by Hooker about '70. Hooker then marketed a line of headers under the Casler brand, why is anyone's guess, but there it is.. So now I am looking for part #'s for JR Hedman, & Casler if anybody has them..any others/ideas out there?
