I'm a big fan of standard cast iron guids.
Saw too many engines with trouble using bronze or other stuff.

Cheers

"Install guides if you are using the bronze guides, they MUST have .004
stem clearance.  The shops take some convincing, but if clearance is less in
these old engines, the heat will cause the guide to shrink and the valve to
stick, perhaps destroying the entire engine."
