does anybody know if somebody like felpro makes a flat gasket intake manifold gasket for pi 4.6 heads. i have a set of npi heads that i plan on hand porting and need a template to bring the intake ports to the pi shape before i can begin porting. does anybody know of any company that makes such a gasket?

 

I'm pretty sure felpro does make one. Autozone carries felpro and they usually have intake gaskets in stock too.

 

you can also go to a ford dealership because they sell a head changing kit which will include everything you need
