LS Swap headers

[67Rally]

I posted a similar question on two other forums, and someone just posted pics of the Dynatech headers in a '69 Firebird with the recommended DSE mounts and 3* trans angle:



I don't have a good machine shop that I've worked with in the area. I'm going to swing by the exhaust shop later this week and see if they have any recomendations. If I mill my current flanges flat, I'll also have to dimple the headers near the PS box even nore in order to get closer to 3* on my trans angle.

If you did have to dimple them more it wouldn't be much unless the flanges are warped more than I'm thinking and they had to remove a lot of material. I haven't seen yours of course but I'd guess it would be less than 1/16" but you could also use a thicker gasket. I think they make thicker ones like they do for head gaskets.

They were going to email him and ask for the pix but haven't gotten back to me yet. I'm going to give them another call this week and maybe you should too. If two of us are bugging them maybe they'll get the pictures.

On another note, can you have a local machine shop reface the flanges and clean them up so they are flat?

I think I know who that is, I'll Facebook him a link to this thread.
