I've noticed all my spare manifolds are warped (as viewed from the side), so the ports don't line up exactly with the ports on the head and gasket. I know the faces can be machined, but can anything be done to bend them back? Thanks. | | |

If it weren't for inlines there would be no fun in wrenching

I don't know anything about the seller or the item. I just seen it and remembered someone was needing one. Joe http://cgi.ebay.com/ebaymotors/ws/e...8&category=33632&sspagename=WDVW | | |

FYI, I just found out that GM still sells the 292 manifold - it has a 3-bolt flange for the exhaust instead of 2, but that's the only real difference. | | |
