Hmmmm... I dunno... I guess a lot would depend on how confident you feel about learning lotsa new stuff in a short time. It's not particularly difficult, no, but I can't say yes or no. My gut feeling is to say no, but the ultimate decision would be yours.

I think by the time you purchased all the parts, Head, gaskets, hoses and belts, water pump, thermostat, rad, etc, you are talking around $800 just in parts. If you have a shop do the work, you are probably talking around $1500 ??? at least in this part of the country.

Do you have tools? There are a few "special" ones you might need. i.e. a 6??? mm 1/2 drive allen key for the head bolts, a good torque wrench, etc ...
