b16a to b17a

Ok, I'm new to H/S and was seeking input on what i'm about to do to a b16a engine. I have a 94 del sol dohc head and a jdm b16a block. I am planning to stroke my engine to 1.7 liters with a crank, piston, and rods that i had got from a b17a engine. Now, i under stand if i use CTR pistons my compression ratio would be 11:1 to 11:4. I also wanted to go CTR on the head also. That will also bump up my compression. What can i do to bring compression ratio down beside using custom head gaskets kits.
