If its the SOHC ZC then yes, you can put a SOHC VTEC D series head on it... The procedure would be the same as a D16A6 (88-91 Civic/CRX Si engine)...

But why didnt you just buy a complete SOHC VTEC engine?

BTW the engine code of the 92-95 Civic Si is D16Z6... This is the head you want to swap onto that block... You can also use a D15B VTEC head, or a D16Y8 (96-00 Civic EX) head...
