Replace Head Gaskets on 5Ton Multifuel

[gusto1]

I need to replace the head gaskets on the M52A2.
Can anyone give some advice on how long it will take and if I'll need any special tools.
Thanks

There a few threads on this, search "multifuel head gasket". It will take every bit of a day, and you need a special swivel socket for the injector side head bolts.
