Yes, i put thin coat RTV on both sides of intake ports.
Make sure bottom of intake man. is not making contact with header tubes.It will cause major vac.leak and run like one legged dog.
Get spay can of B12 and check gasket area,injectors,vac. lines ect.(running)Engine will smooth if leak detected.
Also disconnect injector connectors one at a time and note change in idle speed.Should react like pulling plug wire..
I ended up having to grind on intake to let intake correctly seat.PIA
