AHHH the good old Daytona, I love those cars.
Being the car is so old depending on how many miles it has, and what the original owners have done to it is very hard to tell what needs done if its not running. like CRE said the head is very bad about warping. If you rebuild it, the factory Toyota rebuild kit comes with a good composite head gasket (vs. asbestos original) good up to about 14psi I was told. Check the center support bearing on the drive shaft, if the drive shaft flops around that is a very expensive part, or you can swap out to aluminum drive shaft. Check for water in the back quarter panels through the plastic doors, or rust where the spare tire is. They are notorious for leaking. Osaka.com sells running japan domestic motors for cheap which could be a good way to, but you could rebuild the motor for less and know it is good. :-)
