i have a friend lookin' for some used 460 headers for his mid 70's mud truck..... i believe 260 / 429 stuff interchanges. it's in a 76 ish reg cab SWB f-100

cheaper the better, as long as they are in good working condition

 

L&L is probably gonna be the cheapest....or go on ebay and look around......as long as the heads arent CJ heads the headers will work....

 

the heads are Dove heads....
