Hey fellas hope everyone had a great Christmas and new years. I was given a set of heads off a "optimizer" would there be the diamonds logo like in the valley? I dont recall on my engine when i got it from teds at lease i would hope they would be optimizer heads being it was military engines etc. (I know a year late now to worry right). But these heads arent for mine i was gonna have em checked if i can find out if they are true optimizer heads.
