I have a set of Vortec heads (Patriots) , and they are drilled/tapped for either standard or Vortec style intake manifolds.
Am I better off using the traditional 6 hole intake, or the 4 hole vortec style intake?
After I decide which intake, should I put set screws w/loctite in the unused holes, or just leave them be?
To me, it would make sense to use the 6 hole pattern, vice the 4, but then I ask myself, why would GM go to a 4 bolt pattern.
