Have a set of 454 peanut heads off an 86 c30. They need to go to the machine shop, and would like any recommendations on required work. Budget is tight, but don't want to sacrifice reliability or durability. Specifically curious about the guides and if these heads have hardened seats or not?

most of the heads have hardened valve seats, as always you need to check valve guide clearance and condition
