Small block header identification

[ike61]

Could anybody help me identify what these headers are for? They are definitely small block and not for an A body. One side is R426F and the other is L426E. Thanks!

Summit truck headers

Ike - those headers will fit on any B or E or F bodies. Even later R bodies like Diplomat.
I had a set of those headers made by Casler on my 1976 Volare Road Runner.
The passenger side has to have the steering center link go above the 3 lower header tubes.

Awesome. Thank you so much!
