imho, on a forced induction set up, with conservative boost I would guess that the difference in the two(if any) would be so minimal that it would not be recognized in a marine application- speed wise.

Bling factor and clearance would probably be the difference.

FYI, I have imco powerflows-12 months new.

Good luck

I can't say on the blown application. I have 2 sets on my 454efi's & they look, sound & perform better than any manifold I have ever tried. I have only had Gils, Revolutions & the Danas & out of the 3 Dana is the best. They just look good & perform good too. It also helps that they were the less expensive choice also.
Call Dana & see what they say. They promised me a gain & I got it. I actually got exactally what they said I would get.

I replaced a set of Lightning headers on my 502, look great and perform just as good, if not better than the Lightnings. I was running "almost" dry headers and did have to dump a little more than half of the water that was flowing thru the Dana Vortex risers to eliminate a little reversion at idle. I was looking for this problem from the start and saw signs right off, so I corrected the situation. It was quite easy, I just added an additional 90degree nipple on each manifold behind each riser and ran enough of a restrictor to adjust to just enough water flowing thru the risers.
Great package, great customer service from Dana Marine.
