Cant understand why Triumph did not use valve guides in our cylinder heads



This will make it very expensive as the head has to be replaced, does this mean triumph will of course will keep supplying these for 30 or 40 years



You can get new valves machined with larger valve stems, then hone the valve guides in the head to fit, instead of buying a new head. This will be about 1/10th the cost.
