You dont mention wether it is a V6 or I4. IF it is the V6 the link above may give you some much needed information.
Toyota had a problem with headgaskets on Trucks, 4Runners and T-100's with the 3.0 liter engine. You never know you may be able to get the truck for 500 and have the headgaskets problem taken care of by Toyota.
As for labor you are looking at probably 10 hours worth of labor if you ahve to pay for it to be done. THe one thing to worry about is, will there be other problems once the engine is torn down. I used to be a Toyota mechanic and there were several times we ahd to replace the cylinder heads due to them being warped so far out of spec taht they could not be machined and still be in Toyota specs. There were a couple of times we had to remove the engine block and send it out to a machine shop to ahve hte engine block surface machined be cause it was either warped or there were grooves worn into the metal form collant running between the block and the cylinder head. THis was not a common problem but it did happen on rare ocassion.
You can also doa search on here about 3.0 headgaskets and probably get some reptty good information.
Everything I have said is based on the 3.0 liter V6 engine. Like I said if it happens to be the 22RE I4 engine then none of this will apply for the most part. THe I4 was not very common on the late eithgties model 4Runners but there were some that it was installed in.
