I have a 1965 olds delta 88 with a 455 dropped in it. I can’t for the life of me find any type of header that will fit. It’s seems very tight and the steering column is in the way. Any help would be great!

 

Forget the headers just buy the repro dual exhaust manifolds from Thornton.

 

You can't find them because they don't exist. The location of the steering box and linkage, coupled with the near-zero market for headers for these cars, means that no manufacturer has ever wasted the time and money developing a set of headers just to sell half a dozen sets over the last 50 years. Sorry, but unless you weld your own, the repro factory manifolds are your only option.

 

olds65 i have one of those manifolds here , not sure what shipping would be im just over here on the island

 

Joe said truth. No headers unless you have custom made. An option for the passenger side manifold is the divided Z available from a few vendors as a repro. The drivers S manifold is horrible, but sure beats the old crossunder single exhaust setup. I carefully used a die grinder to do a little port matching and enlargement of the exit ports on both. I used 2.5 aluminized pipes with electric cutouts along with a way-too-big comp cams ***** thumpr. It sounds absolutely outrageous at 1100 rpm. The passenger side with the divider has more cackle due to the isolation of the exhaust pulses. Drivers side S manifold sounds good, but is simply a log type, no divider
