454 Exhaust Advice / Help
So the headers on my truck just won't seal right. I've tried new / better /double gaskets, etc, but it looks like the headers are just warped
Instead of buying another set of headers I am thinking of going back to factory manifolds. The truck is just a cruiser and I don't need the noise and I am hoping factory manifolds will fit better My engine is a mostly stock, mid-70s 454. What is the part number for the factory manifolds? Anything I need to be aware of? I assume the later ones from the early/mid 90s will NOT fit? (I know I can find these at a junkyard) Thanks for the advice |

Re: 454 Exhaust Advice / Help
You should be able to purchase new manifolds from most any FLAP. I did a quick search on Auto Zone's website and they are available between $93 and $120 (depending on side) each.

Have you tried the dead soft aluminum layered ones? They work awesome for warped headers.
Also you can work warped headers back on a belt sander.
