Small block tube header ID Doug’s or TTI?

the jog at the top of the tube doesn't look severe enough, and the 3 & 5 tubes look different but maybe?

TTI's have super thick flanges and should be stamped w/ a PN

maybe some old hedmans? i know that they would frequently incorporate the 3/5 wrap in that style.

if schoenfeld(sp?) made sb mopar headers i'd say them maybe?
