Header flange dimensions

All, I have a friend who works in metal fab shop. He is requesting that I give him something to do to pass the slow times.

Does anyone have a drawing with the dimensions of the LSx header flanges?

If they work out good on his machines, the provider will receive a set of flanges. (First one to PM or email me)

Thanks

Stock manifold gasket FTW...

Do you want a set then? :lol:

Sure...LOL.. 2" OD on the primary size please!

Ok, might take a week but I will see how they turn out.
