i bought an h22a from a guy that i work with and he dosent know what year the engine is i need to find out if there is any way of identifying the year of the engine and if anyone has any links to the install in a 98 civic thanx so much.

The year is imprinted on the front of the head, right above the exhaust manifold. Like this:
