My car came stock with a D16Z6 block. I put a D16A6 block in it. I ran into a problem once I got it all put in. The thermostat housing on the Z6 block has a sensor in it, and the A6 block does not. Should I have a problem if I just leave the connector unplugged?? Also do you know of any problems I would run in to putting this head with this block? I know the headgasket for the blocks are different. The A6 gasket is a single piece, made of that mushy metal like the intake or exhaust gasket, but the Z6's gasket is 3 (i think) really thin sheets of metals together. There is like a $20 price difference in the two. I've been using the cheaper, one piece headgasket, is this the right one??

Btw My car is a 95 civic ex and the donor car was a 91 crx SI (i think). any info would be great!
