upper intake gaskets/engine crud
I ordered the upper intake gasket for my 2001 4.0 v6 Ranger. When ordered it they told me they only sell in sets (upper and lower gaskets) When i took off the upper intake, i see o-rings, not a gasket. Do i use a gasket along with the rings, or did they order the wrong things for me? 
Also when i pulled off the upper intake, the ports going to the valves were loaded with gunk. I cleaned them as best as i could, but i suspect the rest of the intake is loaded with it too. Without tearing apart the whole truck, what is the best way to rid my engine of the crud?
Thanks!!

Berrymans B-12 works great on caked-on carbon crud. Along witha lot of rags and maybe a small brush, throw in some elbow grease and that's how you clean the ports. Try not to let the crap get into the cylinders.
The upper intake "gaskets" are indeed O-rings. The are in fact O-rings on my 4.0L OHV, too.
