If your going to take the time to pull the covers do it right, replace the gaskets with the blue Fel-Pro gaskets, the number ends in a "T", follow their instructions. The other important things is making sure all surfaces are very clean, the covers are flat/not bent were they contact the head, the load spreaders are put back in the exact location, DON'T over-tighten the cover bolts. When I did my 2.9 I was able to get them off by...disconnecting any electrical connections in the way, flipping the alternator back towards the fender, unbolting but not removing the AC, unbolting but not removing the dip stick, and maybe a few other hoses. There are only a few small areas were you need sealer, near the head/intake.

the head gaskets have been replaced numourus times and each time they leak afterwards thats exactically why i am going to put the sealer around the entire surface of both the head and vavle cover contact areas
i want to get this done soon and i could probly get this leak to stop by just putting the sealer on with out a gasket... hence the name "gasket maker" but sence i am going to go through all the trouble of taking this off why not get the other gasket in addition im taking them off the weekend none the less if the gaskets come off intact and look like there not damaged i am most likey just going to put the gasket maker around the area i sed before and put it all back together.

The attention to the details I listed is very important if you want to stop the leak, it stopped my 2.9 Rangers leaks.
Be careful with the gasket maker, the excess that is inside can break loose and end up clogging the oil pump screen.

The Fel-Pro gaskets that end with a "T" are made of silicon or something like it. The most likely cause of continued leaking is warped covers due to over-thightening the bolts, missing/miss-placed load spreaders or the sealiing surfaces were not cleaned properly.
If you read your manual it will descibe the procedure for adjusting the valves, basically with the valves closed you turn the screw 1.75 turns past contact.

Okay, I'm going to have to put my $0.02 in here again. If you want no leaks, do NOT use cork valve cover or oil pan gaskets. They tend to get cut, dry out, get brittle, crack, and leak like a sieve. A cheap fix, if you don't want to spend the $$$ on the permadry plus silicone gaskets, is to get the permadry rubber gaskets ("R") and put some hi-tack sealant on at least the cover side to keep them in place when you re-install the covers, etc. I replaced my valve cover gaskets around 3 or 4 months ago with the rubber ones, did not overtighten anything, and I have almost zero leakage. My other problem areas (typical of both Fords and this particular engine) are very minute leakage at the upper intake and front and rear main seals -- esp. the rear main... a BIG Ford issue since as long as I can remember. Anyhow, no offense to anyone... just my $0.02
