Slant Six Headers

RRR, I know you posted for a 225 engine. But just a FYI, the Clifford long tube headers, are different between the 225 and the 170. Also the Clifford shorties will not fit a 66-down "A" body 225 with PS, or a 170 W/WO power steering. The shorties can be modified to fit.
The Aussie Speed headers do fit with the 170 (I have them on my 66 Valiant 170). Supposed to fit with the 225. also, but I haven't tried.
