hi I am s l o w l y rebuilding a spare engine for my jeep it an old F head it is worth getting the valves and seat hardened so I don't have to add valve master and who would you recommend in CHCH I am looking at doing most of it myself to keep costs down but can't do the machining etc myself or at work but can assemble and store
it is worth getting done if you are pulling it apart a one off piece of mind thing really, Cylinder head specialists do a really good job and are nice to deal with, you could plane a bit more off the head too to increase the compression a bit too it depends what you want out of the rebuild. Relyable do the valve seats and skim the head and bolt it back together, more power take 1 mm, 1.5mm or 2mm off the head to bring the compression up it doesn't take much but you may have more wear and gasket failiures less water compatable too.
