So my 96 Tahoe is nearing 300K miles and the rear is getting really noisey. Dash lights and radio dial lights no longer work and most of the plastic interior parts are either cracked or missing. So, i start looking for a parts truck to fix the old girl up and keep her on the road. i found a 99 LT taho with engine problems and pick it up for $500 bucks. 
I put a battery in it when I go to pick it up and the thing starts right up and I drive it onto the dolley and drag it home. This thing is in better shape than my 96 is and I am thinking of vice versa my original plans. Pulled the heads off of the 99 engine and there it was, cracked heads on #5 and #6 cylinders on each exhaust valve. Water in the oil and intake gaskets have been leaking for a long time on this engine. I have a spare set of heads from a previous project so i am thinking of dropping these heads on and see what the engine does. Only real problem is the #5 cylinder is kind of washed out from a lot of coolant getting in there and sitting for a long time. Question is, will the washed out cylinder wals polish out or will I have oil/ring problems once running? Apreciat the input.
