followers in a ca18det (help)

[mr2sc89]

hello, does any body know that if the hydraulic followers under the cams should be spaced or set up? the follower seems to have no move ment?
the valves have been re ground, i have replaced the stem oil seals a recond the head and ported and polished it, but the valves dont seem to close properly when i turn the cam over, this is present on all valvs? i seems as if the all followers are seezed. the reason i did all this to the head was because in original condition at 3000 rpm plus there was a rattle from the inlet valve on the first cylinder? has anybody come across this before? any help is appreciated. thanks
