I have researched this multiple times with different answers. I have a H22 that is run on circle track. Only ever sees the RPM range of 5000-8000 rpm. It has to be the OEM intake which I plan to modify. For my range, would my options be better to gut two IAB plates and stack them, gut a single IAB plate, or to completely delete the IAB plate with new bolts? I plan to gut the upper portion of the intake and cut the lower portion to the point it is 4 individual runners. Thanks for any input

You should ask Blacktrax or Rosko, they both specialize in the H22 manifolds.

Also look at 220 Racing. They're on eBay and FB.
