Which intake?

I have been looking into getting a new intake and narrowed it down to 2...the Weiand Stealth Air Strike and the Weiand Action+Plus...i was just wondering was the best for the money?...the Stealth is 202 and the action+ is 125...it will be recieving a holley DP 700cfm shortly down the road...it has stock heads milled and the engine is a 350 bored .060 over... its a 5 spd with 3.08 rear gears...im looking to get rid of my tunnel ram and want a replacement that will produce just as much or more horsepower and torque...

Thanks Chas

rpm performer...lift is 234* intake and 244* exhaust both at .050"...112* lobe seperation...edelbrock states that it has about 10-12 inches of manifold vacum at idle....

Then a Performer RPM or Stealth. The air gap type may be a slight advantage, but probably shouldn't be a deciding factor.

I wouldn't pay twice as much for an air gap type intake. But, maybe 20% more.
