does any one know if the ZC head is interchangeable with other d series heads. also if it is what do i need to swap it on to a D15 16Valve. and what year and model car can i get one from

 

Depends. If you mean a single cam ZC head, yes, they bolt to 88+ single cam blocks. If you mean dual cam ZC head, you need to use a dual cam ZC block.

The only exception to the rule are 84-87 single cam blocks. Dual cam ZC heads can be made to work on them with some effort.

Real ZC heads are not availible on anything in the US.

 

thanks
