Good gah-reef! I said, "If you're going to run factory iron............."

I've said it MANY times before........You don't run the factory iron unless you are forced by the rules or your mind tells you, for whatever reason, you just gotta have the factory iron.

I run our ported factory iron because I can show off and make more power than most can with ported aftermarket aluminum. However, when I want to make the most, I'll port the aftermarket iron or aluminum.
