Thread: Crazy Pontiac question

Tweet

I've got some pontiac 301 headers if u want them tell me where you live and i will decide on a price.

That's an awesome offer, but I've got it in my head to make them myself, 100%. I've always thought a thicker flange would help with gasket blow out, so I'm going to gouge them out of a piece of 1/4" plate.

Just info, my pre-made flanges that were the base for my lake style pipes are 3/8" thick.

Thanks for the tip, I ought to be able to pick up some thicker plate at the scrap yard

Use minimum 3/8". If I ever build another set, I'll use 1/2".

Amen to that, that way after all the warping you can swing it by the machine shop and have them surfaced back to flat and still end up with some thick flanges again!
