Sorry if this is a repost but i have been running myself in circles to find these answers.

On an N/A VQ, am i gaining useable power to get the APS Tall boy and a spacer from AAM or Motordyne, most likely the 1/2?"

Am i better off just getting the 5/16" and call it a day?

On Motordynes website they refer to the lower collector on the VQ for non revup. Am i gaining useable power if i purchase the MREV2 manifold on a non rev engine? I did not think that would be functional. Is it worth the money?

I'm trying to make N/A modifications that will still give me power and be functional in case i go the FI route in a year or so.

Thanks for your help guys.
