Ok, here are my 2 options! Which one?

Ok i have a DOHC ZC that i could build for about 1,500 with aftermarket pistons and rods, but i also have a d16a6 block, would it be better just to put the ZC pistons in the d16a6 block with aftermarket rods? Cause i heard it will give me like 11:1 compression like that. Or should i spend the 1500 and build the ZC? I have all the parts for the d16a6(head, block, cam, tranny) So all i would need is the rods! Should i do this?
