Bronze valve guide clearance

[willyp42]

hey guys I bought a set of supertech nitrided intake and inconel exhaust valves with the bronze valve guides to match. I can’t find any recommendations of the guide clearance. Anyone here know?
Thanks.

No one?
i see the factory specs are .02 -.05mm with service limit of .09. (intake) and .05-.09 with service limit of .15mm (Exhaust).
should i just go to wide part of spec? wider?
no one with any experience on bronze valve guides?

I run them but I don't know the specs, my machinist put them in and they are "slipperier" than cast iron guides plus in the unfortunate event that you kiss a piston, they don't tend to crack like cast iron guides tend to.
