can you add material to iron?

add material to heads?

has anyone ever hear of someone adding material to lower the volume inside the head of lets say a 75 455 head?

I guess you could with alumimumn heads but what about iron. I've brazed iron before but I wonder what the temps in the heads would get and if the added material could hold up. its kind of a crazy idea but just wondering if anyone knew if its been done?

I have only seen brazing in the ports, not in the chamber itself.

I'm sure that there is an epoxy the adheres to iron. Advanced porting]

Yes, its possible to add material to cast iron heads.

Yes

 

I was hoping Greg would respond here cause I KNOW that he's done some adding. Porting isn't ALWAYS about removing metal! :Brow:
