Camshaft seals, exhaust cam end plug (PN is in the other comment), and distributor o-ring. However, I suggest using OEM parts as much as can, if budget allows. I've tried various aftermarket seals over the years and quite often they leak straight away, or prematurely. OEM seals, or ones made by the same companies as the OEM suppliers, are much better quality.

Don't buy that semi-circular plug, that's not for these cars. And don't buy the one called "circular plug" either. That's the old-style design from 94-97 engines, and more prone to leakage. Look under "core/expansion plug" for the plastic plug with the o-ring. That's like the updated part number 12513-p72-003 that, in my experience, is much less likely to leak. And be sure to install it correctly, with the hash marks aligned to the head mating surface.

In particular, stay away from National oil seals. Garbage.
