thank you so much for all your help i’m happy to report the guides are out. would you recommend heating the new ones in

A bit late to mention it now but ideally the new guides should have gone in while the head was still hot from taking out the old ones. Perhaps pop the head back in the oven to get it nice and hot again.

Definitely don't put the new guides in cold, heat the head as for the removal and chill the new guides overnight in the freezer. That way they should all but drop in. If you drive them in cold they will almost certainly come loose at some time in the future.

Well done, easy isn't it. Do as DJM says and it's a piece of cake.

new valve guides just turned up and i noticed they are a few mil longer than the ones i took out. Anyone ever had this with replacment guides as there supposed to be genuine parts

Which end is longer? Valve end or spring end?

Over-long at the valve end should not be a big proble but if the spring end is too long it may interfere at full lift.

Probably not a problem, but worth checking.

it’s longer at the valve end. if it interferes with the valve i can file it down i just wonderd if this was normal for replacement parts that are supposed to be genuine
