Pointy/Curvy CCT swap?

Hi guys and unfortunately need a very prompt reply to this.
My bike has recently developed a rattle, i'd developed a bit of an oil leak and oil levels got dangerously low, found the leak and sorted that topped up the oil. unfortunately the day before i refilled the oil it started rattling, i filled it up hoping it would get better but to no prevail. problems then got worse, it started over heating, a lot higher than its ever gone to before but reading on here a lot of people have theirs sit at around that temperature anyway but the rattle seemed to subside and the temperature seems to have now settled back down. then yesterday while out the rattle got epicly worse. it sounds to me like the cam chain tensioners and have as it has somewhere between 25 and 30,000 miles on the clock and its a k6 model on 07 plate. Might be a little premature for it to wear down but the lack of oil probably helped that.
I am looking at changing the cam chain tensioner and hoping for the best. Does anyone know if the ones from the curvy sv will fit? as i found on ebay a pair of cnc machined manual cam chain tensioners which i was about to commit to buy and then noticed it said in rather small writing "WILL FIT 99-03 models".

unfortunately i was ment to be driving half way across the country next friday and need the bike working. Does anyone know if these will fit and work? (i know bidding has now ended but they are still available)

Does anybody know if the curvy and pointy sv cam chain tensioners are the same/interchangeable?

I believe it is popular for people to put K3 tensioners in the curvy, but dont think any after K3 work, sure some one else will have a better answer than me
