headers

[95'sierra]

i have a 95 sierra 1500 ext cab 2wd and the exhaust manifold bolt (furthest rear on drivers side) broke off flush with the head. now i have to take off the manifold to drill it out. while the manifold was off i was thinking about throwing a set of headers on it. now i dont have stock exhaust but my new exhaust i put on is routed exactly the same so iwas trying to find headers that would requre vey little modification. basically bolt on any help would be appreciated
