I've been considering port matching the intake and exhaust ports on my 5.7 liter but I was wondering if it would be worth it. I'm not talking about a full on port and polish butminor grinding to clean them upsotheyline up better and fix any casting imperfections. Think that would be worth it? Also, would there be any negative effectsif I only did the exhaust ports and headers?

For reference my Mag just hit 35,798 miles so game on...... I amgoing to add a cat back exhaust, a K&N intake and get it tuned so I thought maybe it might be worth spinning some wrenches and a few hours with the grinder.
