Anybody know what the real time and/or clock time to replace head gasket on '94 6.5T?

Did compression test after the Tech 1 reading showed codes 92 and 93, had the recently replaced injectors spray pattern tested (good), but the compression tests read 240 and 280 respectivly. So it looks like checking the heads and head gasket are the only option and I need some info. before hiring a mechanic to know the scoop on real time and book time on this procedure, any help would be appreciated.

According to alldatadiy.com, the warranty time is 12.8 hours of labor, and the standard time is 17.9 hours. (This is with 0.9 and 1.2 hrs, respectively, added for A/C). I couldn't tell you how long it actually takes. Hope this helps.

I recently had my heads rebuilt because I burned a valve. I took me about 8 hours down and 8 hours back up, and I'm an electrician.
