98 hx with the stock d16y5 in it that I'm pretty positive is seized up and I wanna put the exact motor back in but I'm short on funds and options so I'm going with the y8 swap. What else should I take off or do i need to take off the d16y8 parts car in order to complete the swap. I have the block and head already, just need to know if i can use my y5 valve cover, distributor, intake and exhaust manifold, etc... Please help.

 

You can swap heads onto the y8 short block and be done. New head gasket and head work suggested.
