Polishing the exhaust port excessively;ie "mirror finish" seems to be somewhat useless since the carbon buildup in the port will negate the finish in a hurry. My intention is to work the exhaust side smooth then leave it. I remember reading a porting article in either Hot Rod, Pop. hot rodding, or Car Craft [yah I know they hate imports but sometimes they have pertinent info & I've been a car mag slut since high school even though I HATE Camaros] & it said that it's more imp. to work on the short radius bend because that's where the slow air is. I'm looking for the article in my "archives"[pile of car mags] & will see if I can give us any more insights. It would be nice to see one of JP's heads to give us po'boys something to shoot for but I don't want to take anything away from what he's done & is doing for our old Volvos. I think he's doing a great thing! I'll get some pics when I'm done with my head but that may take awhile, plus I'm a complete Luddite as far as comp. are concerned [this thing is a 386!]
