Default Intake gaskets differences???

I am installing this miniram, and now I see my 1204 Felpro gaskets, have all ports open, but the ones I removed here in the pic, have only a drilled hole through the back port.

Any help please. Are my new ones going to be ok, with the open passage?


These just came off the car, and only have a small hole, the felpros are completely opn on the back passage.

I don't think the mini ram intake has a back cross over coolant passage built into it so you should be good. Take a look at the intake and you'll know for sure. You'll need to block off/eliminate the coolant's heater hose riser tube that is "T'ed" into the heater hose for the L98 application though.

Just replace the one factory hose with the "T" splice in it that runs to the heater core with some regular heater hose that's the same size.
