Hey Guys. I have always wondered about getting the heads ported and polished. I remember reading in a Mopar Muscle magazine where they used stock 318 magnum heads on a 60s block and after a lot of tweaking and trial / error they had a 400HP engine.

Has anyone had theirs done?

 

I have! It didn't take to long, no noticeable difference but worth it to know you have done something more to help it. At the same time I did my headers, and intake. I didn't do as much polishing as some do just so I could squeeze in time for all pieces.
