69 292 Exhaust Manifold

[Doubletrouble]

I've got a 69 Chevy C-20 that is my workhorse...pretty much stock. I replaced the 292 engine with a rebuilt 292 some 22 years ago and the exhaust manifold was cracked. I put headers on it and they have worked well. However, I am going through exhaust gaskets right and left and am thinking about going back to a stock exhaust manifold and exhaust. I have had to double gasket since the beginning (Mr. Gasket #155). The engine that is now in the truck is a 71 or 72, I believe, although the intake is from the original engine. I found this exhaust manifold on ebay: http://www.ebay.com/itm/65-66-67-68-...#ht_1215wt_791

However, I don't know if it will work on my earlier model. The intake is stock and the stock tranny is a 4 speed transmission. Any thoughts or suggestions would be appreciated. Thanks!
