I have a 92 f150 with a 300 6 that I restored and when I took the valve cover off to paint it and replace the gasket i found coolant laying around 4 of the head bolts and "carmelized" oil on the rocker arms and on the inside of the valve cover. What would this be?

smoked head gasket, warped head, cracked head.

I'm going to get a flush and fill on the cooling system of the 4.9L in my '95; first time I've ever done this. I've heard horror stories about flushing a hot block with cold water and cracking the block. Is this a serious worry anymore? Planning to have the work done at a Meineke shop.
