Sorry about these stupid questions. Just don't want to screw this up. Bought a FelPro gasket kit from summit, and the headgaskets say Front (on both sides, of course), but I can't figure out which side is up.. It does matter I assume? One side is grey, and the other side has a bunch of lines..

And, I asked in another thread but might as well ask here, I should only apply rtv to the long bolts, correct? No chance of the other holes somehow having a leak into a water jacket? Thanks guys

Just put the gaskets on the block with "FRONT" at the front on both sides. That means that the gasket on one side will look upsidedown compared to the other gasket, but that's the way they are supposed to go. It doesn't really matter on those gaskets whether the grey side or the lined side is on top. If you do it any other way, certain water passages will be blocked and the engine will overheat in minutes.

No need to use sealer on head bolts, they aren't exposed to the water jackets. Just need to use a little oil so they torque down correctly.

the early 302s you need to flip one side over and reverse it... just look to make sure the bolt,coolant holes line up....

Thanks guys. It's an 88 5.0. I can definately see that the longer bolts seem to go into the water jackets. The smaller ones seem to be blind holes though. So definately doesn't matter that they are upside down then eh? Cool.

On the 5.0 - you'll need some type of thread sealant on the holes hitting the water jackets. I just used some RTV blue on mine - been holding fine for over 40,000 miles.
