Swapping head

Swapping head
Hello, recently got a CEL on my vehicle (2001 apt with 101k).
CEL was solid then started flashing after driving then would stay solid (very on and off)
had my mechanic check it the cel was for a misfire in cylinder 4. We then did a compression test he said it checked out normal and then did a valve adjustment after that CEL went away for about a week and then came back.
Originally thought about getting supertech upgrade (valve spring retainers). But not sure if that would do that trick.
My mechanic then suggested about swapping an ap2 head on the ap1 block.
Im sure there are many threads already on this topic. Just did this because its easier to keep up with and I got every question I can think of (and will ask if anything comes up) in an organized space.
Also I do not drive the car everyday.
Any suggestions, opinions just looking to keep the car mainly stock and wanting a nice car to occasionally beat on. Thanks in advance.

No supertech valves dude. Just don't. Keep it stock.

Compression checks out, but you want to change the engine, when it could be that all you need is a computer, or new coil pack. I'd get a second opinion if I were you.

Interesting diagnosis...
First off, was the valve adjustment done on a cold engine? May want to double-check it if not.
If I were you, I'd swap coil packs around (track where #4 goes) and see if the misfire moves with the pack.

What CEL did you get? What does it say your problem is?
Going all the way to swapping a head before you've gone through all the diagnostics is extreme---I agree with Slowcrash---get a second opinion from a different mechanic.
If you don't know any with experience with S2000s, post in your local forum and ask others who live near you for recommendations

going to ask him exactly what code it was. also i have driven the car since this problem has come up (very local just in case). and the car drives fine. sometimes the ideal drops a little but nothing crazy and for the most part drives like when i got it.
will try swaping the coils around when i get the chance.
also thought of supertech as an upgrade and possibly something that may be a little more durable. should i stay OEM and why?

Moving to supertech has trade offs. The supertech valvetrain will be made of titanium so it will be more robust to valve float but it will actually wear faster than OEM components. If you would like to upgrade the intake retainers just go with Ap2 intake retainers. OEM is the way to go unless you are going FI.
