d16y8 head and intake mani will if fit on d16y7? do i need to replace(ecu) somthing or just straight swap? help pls thanks!!!!

 

It's pretty straight forward, if you're doing it to add the VTEC onto your non-VTEC engine it's called a mini-me swap (putting a VTEC head on a non VTEC engine).

There's some good write ups if you look around.

Here's one that's specific for your engine.

Also might wanna refer to this one from time to time if you get stuck - I feel it's more thorough. Please note that this one is for a 92-95 though, the principles are the same, I would follow the 96-98 one (the first one) - but if you get stuck, you could always look at that second link and see if you can find an answer b4 creating a topic.
