Marcel:
I believe the head your were running on your TR3 was one that I did
and sold you a few years back. Can't remember if I installed cast iron or
bronze guides for you. If they were cast iron I reamed them for .001"-.0015".
If bronze I usually ream them to .003"-.0035" for added clearance. It would
take a full hand of fingers to count the stuck valves we've had with bronze
guides reamed to stock spec's. Hard for me to justify bronze guides when I
have to ream them to worn out spec's to get them to work. Oh, and they cost 5x
more than cast iron.

In the Triumph
Service Instruction Manual, 0.001" to 0.003" is recommended.
Maybe steel valve
guides will cause no problems,but I believe bronze guides
should be reamed to
the original size after fitment

Clearance
Is there a recommended clearance for valve guides? I may have a
valve
sticking.
Engine builder just put in oversized valves and new guides.
Thanks
