rebuilding my KA24

[Sleeksil80]

with over 200k on the motor cylinders 1 and 4's compression is shot. So while im re-building i figured it would be a good time to do some upgrades, nothing crazy, 3 way valve job, bigger valves, springs, retainers, cam, and possibly pistons.

any suggestions as far as a good stretable settup? i was thinking nismo, just because its nismo, but i havnt been able to find anyone who have used nismo internals to judge if its worth it.

anyways, any help will be appreciated.
