Mine is a 3.9 early 90's so are we saying the Rimmer bros ones. I'm confused, but that is easy at the mo!

The ones I was referring to are for the later guides with the stepped top 0.5 will be a looser fit IMO we don't want these little blighters creeping off the guides cant say I have any time for the earlier guides that used those silly washers

I believe Rover spec of the recessed top is 0,495" so 0,500" seal should stay put (they are definitely not easy to push on).

This is what I done in the end !
I made a spacer out of a bit of gas barrel to slip over the valve guide so that the cutter stopped at the required height , then made up a chamfer tool with a tiny lathe tool jubilee clipped on ! I then found the Vauxhall/Opel valve seals were too long, put them in the lathe and took 2mm off the bottom, made up a tool to drift them on out of a bit of door panic bar tube ! they were very hard to get on even with the drift and oiling first. a lot of fannying about, but its done now, only cost was the valve seals.
I thought I would post this as Ive asked a lot on the forum lately and would like to put a bit back ! thanks for all the replies

Good looking, neat work!
I like the tooling you made, too. Very well thought out.
