I'm working on a 79 TA with 6.6 403 OLDS thats the problem. I ordered headers 70-81 326-455 they wont work because of the olds engine. Now my question theres a set of headers for Cutlass, Firebird, TA.... 77-78 this TA is a 79, its the only set I can really find in the price range for this guy, will the 78 headers fit a 79?? I dont know why they wouldnt. Thanks, Paul

They sound like the dynomax headers. Is that right? I wil tell you that I got a 77 T/A that had a 403 in it. I used those dynomax headers and they fit fine. Then I swapped motors and put the engine in an 80' T/A. I used the same headers in that car also. Sounds like they will work. I will also tell you that I have to remove the starter completely and the oil filter and oil filter adapter to put the headers in. Then after they are bolted in, reinstall the starter and oil filter adapter and filter. Be careful of the adaptor gasket. It can fall of the adaptor easily and may not get re-installed. I prefer the factory metal gasket over the aftermarket paper gasket.
