So i have my exhaust mani and intake mani disconnected , removed the cams. And now im sort of stuck\ diddnt have the tools.

Got to buy a 10mm allen wrentch for the head bolts

BUT my question is, on the timing chain after you remove the top cover "two cams and one more gear"

How do i remove that shaft and what is it? "the shaft under the two camshafts"

answerd my own question after reading around alot more i believe it is a idle'r pulley. So can i remove my head without removeing the idle'r pulley and chain?

Yes you can remove the head without the lower timing cover. What you need to do is cut a v-shaped piece of wood to hold the chain tenisioner in place or when you remove the bolt from the idler gear the tensioner will push all the way out. I put paint dots on the chain and gear just to make sure everything lines back up. Whiteout works good also. I hope this helps.

^What he said. I used whiteout to mark each sprocket thing and where it goes...oh and you're going to need the allen adapter that goes to a wrench..don't just buy an allen wrench, since when you go to put the head back on you need to use a torque wrench to have everything go back on to oem specs or you'll have issues..
