You could get a piece of thin plastic hose (like what you would use for bleeding the breaks) put a plastic golf tee in one end steel nail in the other (must be air tight at both ends. Now stick the golf tee in your ear and put the nail on the front and back rocker covers.
You will hear if its your tappets as they are quite high pitch sounds, deeper sounds are usually worn cams. Also good for checking for worn pullys and waterpumps, just be really carefull around moving parts.
Be careful if you make it right, it can be really loud!!!! So safety first you don't want to damage your ears and you take this advice at your own risk!!
Alternatively go buy an engine stethiscope and use that instead.

Are you sure its defo the tappets, i had a problem with one of the Vris solenoids (two small black things above the rear bank with little black rods inside but visible) which was loose inside and making a loud noise when i revved, do u notice any gaps in power through your rev range?
Just another thing to look at…
ive put the wynss treatment in and it hasnt made any difference . i think the noise is coming fromthe rear bank . when the tappets was noisey you could hear them when its idleing but i cant hear a thing is only starts when i get to 2500-3000rpm … what else can it be ...
what is the vis valve thing .. where is it any pics any body..

Vris are located on the back of the inlet manifold and are tiny cylinder shaped.
When did you last do an oil change?? (miles ago), what grade oil are you running in your engine?
Also did you use wynns professional HLA treatment or just normal wynns HLA treatment?
I used to have noisy HLA's but they are alot quieter now, still get it occasionally but its getting better with each oil change, I do change mine after each track day though LOL!! I've tried all sorts of different makes/grades of oil and the best one and the one I currently use is mobil1 0=40w
Could be worn cam.
0w40 that stuffs not cheap I use fully synthetic 5w30 with the Wynns treatment that comes in the Can not the Bottle.
i use 5-30 oil castral magnetec wynns out the bottle had an oil change about 2000miles ago,
but ive topped it up twice since then because of rocker covers gaskets leaking. and i cant afford to do them yet..
