Need help changing engine in a 1999 Montana

[DrummerBoy70]

I have a 99 Montana with either a blown head or intake gasket. I'm thinking of buying a used engine and swapping out the blown one. My question is does anyone know if there is a site online where I can get a diagram and instructions on how to take out the old engine and replace it myself?

Probably would be easier to get a shop manual from your local auto parts store (Haynes) or Chilton manuals
