Header brain fart

RRR, would you by any chance, off the top of your head, know what headers I should go with? I found TTIs website and they are saying they have a set but I'd like to get actual users advice first

I don't "KNOW" that the ones you have now won't fit. I think you need to call Dougs and see what they say. I cannot imagine what differences between 72-76 would disallow them from fitting.
