47 FT LBS TORQUE.is for the 1.5 and 1.6 engines 2.2 is 78 ft lbs and the 2.0 -2.1 is 49 ft lbs. the crx engine is 47 ft lbs
SOURCE: I have a 1990 honda civic. I just changed the head gasket
The book say to do it in 2 steps up to 48 ft-lbs. Personally, I would do it in 3 steps, 15, 35, and then 48. Start in the middle of the head and criss cross out to the ends, and repeat.

The head bolt torque is a three step procedure:
1. 29 ft. lbs.
2. 51 ft. lbs.
3. 78 ft. lbs.
See image below for torque sequence.
I hope this helps.
