I had one of those FelPro valley pans. The ports were stamped but not removed. One of them blew out of the valley pan, went through the exhaust port, traveled down the header, and took out one of my turbos. When you've got a turbine blade spinning at 100,000+ rpm it's not a good idea to toss a little chunk of sheet metal in there. We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind. - Stu Harmon

I may be able to have the ports on the intake welded shut instead as my heads are cast iron. What driving conditions benefit from having the exhaust crossover open? Is it needed?
