It's been a while since I've worked on a Honda (spend more time with V8's) but I think you can't mess up the timing by just changing the distributor. Unless you removed the timing belt you should be just fine, if anything the distrubutor might go in 180 degrees out and if that's the case just spin it around the other way. I'd offer my assitance but I have some car work of my own to take care of tommorrow.
