Just purchased a 97 XLT 4x4 and need some help
 

Just purchased my Ranger with a 4.0 V6 and need some help. I purchased the truck with a leaky head gasket and was wondering who makes the best service manual(other then Ford$$$$$) that will have all the info I need do the reapair.

Also, the truck has high mileage (199K)and I plan on doing both gaskets since it's apart. Is it easier to put the engine or do both heads in the truck? Any help would be great.
