I had a 92 PU before I bought my 96 Runner. The previous owner replace the head gaskets and then about a year after I bought it I had to replace them again. At least Toyota went half on the price of the second replacement. The gaskets burnt up so bad that I had to get my engine rebuilt. Very costly and I have tried to stay away from that engine ever since. i don't think I have ever ahd so many problems out of one engine, especially not a Toyota.
