My 600 Holley Carb on my stars and stripes had a 2.9 power valve and the carburator kit came with a 6.9. Does anyone know why this would be? why would this matter?

Did you get a marine kit? Mine came with a 2.5 power valve

2.5 also for the 4160 on my '93 Ford 351W. I'm about 100% sure that the 2.5 is correct for my application at least.
