Does anyone have an exhaust manifold or know where I can get one for 69 H/O? Its all original and I would like to keep it that way! Thanks in advance.

from what i remember on the 69 H/O or at least on mine it is just the w/z exhaust manifolds. Cutlass, 442, w-30 and the H/O had them. if you want i put headers on my 69 and i could sell you mine. Ony thing is one of them has the bolt casing broke off but just needs welded together. Honestly when i had it on there i just bolted it in place...

According to my book the '69 H/O should have driver's side is part # 403003 and is the same for '69 4-4-2 w/ 400-ci V8 and '69 H/O. The passenger's side is part # 402394 is the same on '69 4-4-2 w/ 400-ci V8, '69 H/O, '70-'74 F-85 platform w/ 455-ci and dual exhaust and on '70-'74 full-size Oldsmobiles w/ 455-ci.

The "Z" manifold is the same, but the "w" manifold has a part # of 412287 and was only used between '70 and '74 on the F-85 platform with 455-ci and '72-'74 full-size Oldsmobiles with 455-ci (dual exhaust) They will physically, fit any second generation big block. Also these are the part #'s I've listed and not the casting #'s that are cast onto the manifolds.
