got a lot of cross breeds that run around here chevy bullet/mustang body.
everyone of the sbc/ford combos i saw was custom made headers...
now they have had good luck putting off the shelf 55 chevy headers on the big block car..
also you need to go ahead and pLan on putting a AJE k-member on it...save a lot of header space and lose some weight..
