I recently put a new motor in my 69' grande and the special headers i had to use, because of the GT40P heads, are hitting my shock tower. I can't be the only oe thats put these heads in a 69'. I need to know what brand or what kind of headers people have used to fix this. The brand i have are BBK 1515 shorties. Thank You
 
Surprising that they hit, in a car designed for a 428 engine.

lol, I was 2 seconds from the BFH route untill i decided to post on here. It surprises me too, its like the primaries on NO.1 and 2 cylinders come too far out instead of just doing a 90 down. so does anyone have experience with macs or the other ones?
