I have a 98 Prelude Type SH and the head is ****ed up

As you may know it is a h22a4 motor but i cant seem to find any stock h22a4 heads around where i live but i have have found plenty of h22a1 heads for good prices.

My question is, exactly what has to be done to do this swap?

I know that the head will bolt right up but my concern is with the distributors and ecu type stuff....

I will putting a h22a1 head on a h22a4 block and the h22a1 head is obd1, so would i use the same distributor i have or do i need to rig a obd1 dizzy into the prelude to get it to work?

This is my biggest concern so any help would be greatly appreciated.

 

need this question answered as soon as possible before i make a bad purchase......thanks
