As mentioned hooker super comp #4202 fit 70-81 Firebirds, they are listed as 70-74 due to the O-port shape but fit all 70-81 with O-port heads.

I have them on a 72 Firebird with an E-head 400 block stroker, fit great overall with no problems getting a full size pontiac oil filter in/out.... only complaint is that they do hang down lower than most other headers due to the big tubes & collectors.
