Just a wild guess - possibly Kibblewhite bronze manganese guides. If you don't know or can't find out who did the previous head work, measure the od of the tops (seal surface) and check their website or give them a call. If all else fails, you can buy the tool and turn them down to .420 like stock.

does not necessarily mean it is a stroker, but may want to investigate
For some time (awhile back) we built stock engines with S&S rods (Not Supremes) good choice, back then anyway..
