Alright so i got my portflow head back and im looking at my edelbrock intake manifold and i'm seeing that i'm going to have to port match it at the least. I don't see how i would get the proper gains from a pnp head if i don't. But some older guy was telling me i should send it to get it extrude honed(spell check). He said they shove some stuff threw it and it makes the whole inside smooth. Does anyone know where i can send my intake to get this done. He said the people that do it have to have a special adapter because most of the shops around here only mess with mustangs and stuff. TIA
