Purchased a scoggin-Dickey intake manifold for my 91 tpi firebird. I can't figure out what goes in the 3 larger holes to the right and left of the CTS and water inlet. Could someone help?
You can plug the empty holes with npt plugs. The one on the passengers side is cold start injector timer switch 85-88 tpi. The other must be a option for the cts or water outlet but you have those covered.

Water bypass port to the water pump when using vortec heads and the cold start switch.
