    G'Day Ian,
    Yes it is. I would suggest getting hold of a repro manual from the 
LRSOC shop. Exhaust valve seat removal is fully described, along with 
the dimensions for a new valve seat putting in tool. These seats are 
VERY hard and do not respond well to hammers, getting them cocked 
sideways in the hole etc. The old ones often have hairline cracks in 
them and it is well worthwhile replacing them when the valves are being 
replaced. Note that the LRSOC shop also sells hardened exhaust valves to 
suit the use unleaded petrol.
    In the case of engines with hardened seats, it is often the valve 
that suffers with the use of unleaded fuel. The valve sets in early Land 
Rovers are hardened as noted previously. The same problems arise when 
using LPG fuel, the LRSOC has had exhaust valves made from similar 
material to that used for valves used when converting to LPG.
    Note that the best way to check the condition of the valves would 
HAVE been to have done a full compression test before youn removed the head.
    Cheers
