Valve clearance check and adjustment for the d15b2 motor with the exhaust and intake regulations.
I suggest that you call the auto supply stores in your town such as Kragens and Auto Zone and ask if they have any "Auto Repair Manuals" for your car and/or the car that the motor was in when it came from the factory. In your case: the d15b2 motor came from the factory in 1988-1991 Honda Civic LX models. You would need a repair manual for the Honda Civic mentioned above. If you don't want to pay for the manual--just visit the shop and copy the info. you need. However, the manual would come in handy for other uses so I advise you to buy a copy of it.
Valve clearance specs, along with other useful information, are usually on the underhood sticker. Does your car still have this sticker? Eric
