1.5l mitsubishi motor value ticking

hello everyone to start i would like to thank anyone with the help and information i am about to receive so thank you very much its greatly appreciated, ok i have a 1993 dodge colt made my Mitsubishi it has the 1.5l motor its manual and has about 220,000 i just bought it not to long ago, the head gasket is leaking oil a little but not bad enough to be in the radiator or and mixing at all. the head has been planed down and the gasket was fixed once before to just try to solve it real quick because its only for cumuting i figured i would try and tighten the head down, specs was like 73 ft pounds and i brought it up to 90 torqued in right order and everything, now it sounds like i have values floating , at certain rpms mainly all but noticeable difference it makes a ticking noise i adjusted the valves to specs and its still doing it i pulled all the plugs and from what i can see no values are hitting (i have a snap on camera as well) not really sure what else i can do other then a head gasket and new bolts and such i would appreciate any and all help thanks and so you guys know i have a 2 year automotive school and i am currently attending UTI
