Engine performance issues

[munchkin13]

Hello guys
Don't really want to sound stupid but; I have a 182 which in itself seems to run fine no engine lights but the cams don't sound like there opening fully on the "5k" kick
Can't really feel it or hear it, against listening to two different 172's and can hear and feel the kick
Where should I be focusing my attention to
The dephaser isn't noisy only the slightest but I mean the slightest

Any mods like intake or exhaust?

Maybe have the car checked over?

That's my plan, anywhere to recommend in near North kent
Just thought I might be missing something simple
