Has anyone tried these on a HP500 carb? I'm wondering if they work?

I used canfield 1inch space plate on my 500hp , great throtle response 12 hp gain on the dyno, 85 bucks, call burke power@513 942 5117, ask for bill

Thanks Guys,
Mike, I'll look into the High Velocity heads and see if they are making anything for Marine/Mercrusier apps. And yes, I think it would require a Fuel hard line replumb, and what I'm more interested in is do you have to re-jet after install. I'll check out the bruke power guys also.
