I have a 1997 mustang gt that I am replacing the intake manifold with a dorman. The intake manifold already had the gaskets inside of it, (I bought it used) do i have to put gaskets on the engine heads or will that be double gasketing? Pretty much asking if I need Redirect Notice and Redirect Notice

Gaskets inside of it? What do you mean? You will need those intake manifold gaskets you put the links to.

The links I posted are two diffferent ones, I have a set of gaskets on my heads and inside the bottom of the intake manifold.

You will only needs these gaskets for the Dorman intake Redirect Notice. Just make sure the head surface is clean. You could use a bit of silicone around all water ports just to be safe. Might have been me but I did notice a decrease of power with the Dorman intake. I sold it within 1 month and bought the OEM. Good luck!

There is a big difference between Dorman intake vs OE intake. The Dorman intake uses gaskets that go inside the manifold vs the OE intake that uses gaskets that sit on top of the head which is the ones you probably know.

I dunno why people want to use the Dorman. *The difference in price between the Dorman and the FRPP isn't a lot.
I could be wrong on this... I can't remember exactly, but I want to say the shape of the ports on the Dorman is for the NPI heads?
Either way... f*ck Dorman intakes.

The Dorman intake has what they call integrated gaskets (meaning inside). No need to buy extra gaskets only if they look worn or torn.

Since I was bored, I searched Dorman intakes on Google. This is interesting:

This review is from: 1999 Ford Mustang GT 4.6L V8 2V SOHC Intake Manifold
Visually, the quality of the Dorman 615-175 intake's material and workmanship seems to be better than the Ford stock intake on my 2001 Mustang GT. The Dorman intake uses an aluminum crossover as opposed to the unreliable plastic crossover on the Ford stock intake (Ford corrected this problem in 2002). The Dorman intake also uses integrated O-rings instead of traditional gaskets, which simplifies installation and probably improves reliability (traditional gaskets is that they have a tendency to trap coolant between the gasket and aluminum cylinder head on the Ford 4.6 liter engine. Over time, trapped coolant can eat away the aluminum).

Although installation required many steps, it was straightforward. I purged the fuel pump, disconnected the battery, drained the radiator, and removed the following: upper radiator hose, temp sensor, alternator, intake plenum, throttle, EGR, fuel injectors, ignition coils, and some emission hoses. After I installed the Dorman intake, my car ran beautifully.

Couple of weeks later, I decided to change the spark plugs. However, I unpleasantly discovered that the Dorman intake partially obstructed 2 spark plug holes on the passenger side (the rear 2 spark plugs next to the intake passages marked with torque sequences 4 and 8). The obstruction was enough to block out my Craftsman 5/8 spark-plug socket, which means that changing these 2 spark plugs would require removal of the intake manifold again ... an unreasonable expectation. This problem did not exist with the Ford stock intake.

If it weren't for this flaw, I would rate this product with 5 stars.

I guess he better make sure to use good platinum plugs during the replacement so it would be a long long time before you have to replace them

When I bought my Mustang in 2008, my stock intake manifold broke within 2 weeks. Thinking I would save a few bucks, I did purchase a Dorman intake. What a mistake that was; the fitment was terrible. You have make sure you align the intake otherwise, its a nightmare removing the spark plugs due to the plastic of the intake hovering over the spark plugs hole. With that said, I bought an FRPP intake with the upgraded aluminum cross over and haven't had a problem since.
