I'd say it's worth checking them out thoroughly while they are off. It's no good not being sure when that much work is involved! The comp ratio should also be properly worked out, or it's just a guess.

measure your old gasket, then when scimmed.
ask the engerneering place how much was taken off

Full overhaul is around £150 ( strip clean build, cut and lap valves and seats and surface heads inc vat ) Another £60 ish for shimming clearances, £80 ish if the guides need doing.. Comp ratio 8 to 1 to 8.5 to 1 is manageable.
