1996 Isuzu Amigo heads

I dont know what any book says, but it took me about 15 hours to R&R the head on mine.
Hint: totaly remove the exhaust manifold from the block and pipe, disconect every vacume hose from its port on the intake and mark them with numbered masking tape snips. Lift off the head and intake as one unit and move it to a table where you can do a secondary teardown till you have the head alone.
Once you start this job commit to it and dont let it drag out or you will get totaly confused going back together.

Good luck, and remember, were all counting on you.
