I'm looking to purchase a 1994 4Runner 3.0 4wd with 206k. The paint is shot but the body and interior are straight and good. It has a burt valve on #1 cylinder so it needs a top end job. Dince I'm in there I'll probably do the timing belt. With 206k should I just overhaul the entire engine? What does it cost these days to get the head work done? What's the most I should pay for the vehicle? Any opinions or insight would be appreciated. Thanks.
