How much grief am I looking at replacing the 5.0L stock intake gaskets? My lower has been leaking for a long time. Just drips here and there. The leak has been bothering me since I got the car... The rear main seal is new

There is a felpro gasket set that has thick silicone for the front and back (instead of cheap cork) #MS93334
Should I add some black rtv for insurance?

The 3rd post from this stangnet thread is pretty comprehensive:

But it says to use weatherstripping adhesive on the head-manifold gasket, does that mean cover the whole gasket, or just a couple spots?

I was going to get the injector orings and pintle caps also.

1. Any tips?
2. I've done everything else myself, but should I get a shop to do this?
3. How much should it cost?
