built not bought
Okay mopar owners. I need some guidance, I purchased some promaxx 440 heads. Am going to port match the intake to my max wedge indy intake. And clean up the casting. My question is about the exhaust. I was reading in a mopar book that you don't want to port match the floor of the exhaust(okay to do the sides and top). This was on stock heads though. So is it safe to port match the exhaust on these aftermarket heads or stick with just doing the top and sides? Thanks any advise is appreciated. Pictures attached
