Spend the extra money, buy the hooker super comps for the ventura application, and in about 45 minutes you can have them installed and be on your way, no dents, dinging, bending, bfh's, nothing. Best damn header for an x-body, d-port period.
Now put on a set of e-heads and try to get a set of the hedman race headers from a 68-69 firebird, thats suppose to fit the venturas also, to fit the same as the hookers, is a whole nother story
