since you are taking off your head, it is always a good choice to put a new timing belt on, plus i am not sure but the timing belt may be a diffrent size when you go and swap heads, someone correct me if i am wrong. Also on manual hondas, if the timing belt breaks, you will have to rebuild the engine, because the valve will stay open and the pistons will hit them and bend a valve or break the piston, conection rod or what not. Just change the timing belt, it is cheap insurance. The honda oem ones are like 50 if not less, and the aftermarket brands are even less.

Are there any other major problems that I could run into? Will the head bolt on directly, I have intake,fuel rail,and ECU:complete top end motor as far as that goes.

Thanks for advice. I live in very small town where few know what they are really taking about.

i know for mine it was a direct bolt on deal ... there was a little oil pressure valve thing on the block that had to be removed ( just pull it out with some needle nose pliers ) other than that you look like your all set i'll try to find some info on that exact setup for you though

What about the oil squirters for the pistons? I know the non-VTEC motors lack those. Has anyone heard of their pistons getting scorched?
