D15 block with D16 head? Possible?

my bottom-end is dead in my 90 EX but I found a 91 CRX DX with a good bottom end. Is it possible to use the D16 head on a D15 block? What mods would I have to do? I remember when I had my 1st Gen CRX (I'm fastandfurious1stgencrx from CRX Resource) it was just a piston change and something else to make my DX replacement block work with my Si head. Is it even possible with this engine?

yea it should be, cuz they use the same head. granted the 1.6 has a beefier bottom end than the 1.5, but the heads are the same (the 1.6 head just has a more agressive cam thats all really). So the car probaly won't be as fast but it will get you were you need to go.
