I'll bet our new member's (welcome) 64 Valiant has a 170 slant. There are no headers for a 170 in any car that are a bolt on. The 170 ports are approx 1.5 inches lower (and slightly more toward the driver fender) then the 225, due to the shorter block. Any header to be used on a 170 will have to be modified.
Aussiespeed has a header That is supposed to fit with the 170, but the early ones did not. Check with them to verify.
