Mazda 626 2 liter engine
 

Hi guys!
I own a '87 mazda 626 with a 2 l diesel.I want to make a swap for a 2 liter 8v gasoline engine.And here is the question-16v engines are hard to find,but the cylinder heads from them are easy to spot.Will a 16v cylinder head fit on a 8v block???
I want to gain some power from that mill
