Air Gap vs. M1 Single Plane For Stroker

Hey guys, I have both an M1 single plane and an Air Gap on hand. Just trying to figure out which one will be faster. I'm kind of thinking the Air Gap. What do you guys think?

Here's my combo:

72 Dart, pretty stock body/chassis for the time being.
340 based 416 stroker, forged internal balanced Scat reciprocating assy. Dished forged pistons. About 10.5:1 with the zero deck and MLS gaskets.

Basically out of the box eddy heads. With a spring upgrade for the higher cam lift. A little mild port cleanup but nothing significant there.

Cam is a lunati voodoo hyd flat tappet: Duration @ .050 (Int/Exh): 242/252; Gross Valve Lift (Int/Exh): .533/.552; LSA/ICL: 110/106; Valve Lash (Int/Exh): Hyd/Hyd; RPM Range: 2500-6600;

I have 1.6 ratio Hughes rocker arms. So real lift is 568/588.

8-3/4 axle, 4.11 gears

727 trans, PTC 4200 converter
1-7/8 to 3.5 hedman huslers
750cfm race demon


This is primarily a street toy, go to the coffee shop, Friday drive to work kind of car. Will see very occasional strip duty but not that often.

So, which intake wins?
