I will be putting my MACs w/ ORP on one day and I wanted some info on AIR gaskets. I'm not sure how it is stock, but since I will be doing the AIR restrictor mod will I need two gaskets for each side? These are the part numbers that I have:

AIR Gaskets: 12553617
EGR Gasket: 12553047

Are those the only gaskets/parts I need for AIR and EGR when installing these headers?

Thanks.

 

I run a gasket on each side of the restrictor plate. So, that'd be 4 AIR gaskets total, and one EGR gasket you need.

 

Awesome! Thanks.
