Probably the easiest way will be to release the nut,spring and pin in the centre of the tensioner so it doesn't ratchet up any tighter, put it on tdc by the marks on the crank and no1 on the exhaust cam is flush with the gasket surface at the front of the head, ZIP TIE the cam sprockets to the chain then remove the damaged cam bearings/cam holder,
when reinstalling be sure the cam is located properly on the steel guide under the ball bearing, or you will crack the newly repaired piece
use the service manual to check installation of the cam bearings, and don't loose the 2 locator tubes
when its bolted back down and done with an INCH /Pound tensioner or just firm recheck cam timing then reinstall the tensioner spring centre pin and retaining bolt ,release zip ties and fit the cam cover.
