I Have maybe a dumb question, I have an 88 crx si d16 block that has been bored 30 over with new rods and pistons in it. I had planned to swap over my sohc head to that block and go with it, but I recently acquired a full D16a1 motor out of an 89 teg. Will the D16a1 dohc head bolt on to my d16 si block. I would like to use this block so not to waste the machine work and parts in it. I do have the D16a1 block if absolutely necessary.
