Are you torquing the head down in the correct order?

when you replace it get the head skimmed to accept the new gasket and on the top of the blockget the pistons level (use the cranking handle to get em all in same position) stick something in the cylinders to soak up the fluid and use something like alloy wheel cleaner and a bit of emery paper to get the top of the block looking like new then when you refit the bits get an old head bolt if possible and grind a channel out of it and go down each thread hole and once you've done one hole clean the bolt and do it again with the next one, when you've done that refit the gasket with an adhesive caller "Hermatite" which will help to seal any gaps, tighten bolts in sequence and torque it down proper. should do the trick

The land-rover came with a faulty head gasket out of factory, your best bet would be to buy the top of the line aluminum or metal after market gasket, be sure your mechanic torques down the head then he loosen the bolts back and brings them back to correct specifications and torque in a star pattern. The purpose of the first torque down is to seat it correctly ant the second is to hold it in place. Look for Grey oil in case of internal leaks also be sure not to runt he engine to hard for at least a thousand miles of replacing the gasket.

The cylinder head gasket keeps blowing becuase the head is warped.Get head pressure tested & skimmed.Fit thichest gasket available.make sure bolt holes are free from fluids and threads & underside of head is oiled.Check radiator is not blocked & thermostate is opening.Also make sure there is no airlocks by proper bleading.

after refitting a head gasket, they are more likely to go again, until the engine has been properly run in.
i would make sure that who ever fits Ur new one makes sure they do it properly,ie tightening the head bolts to the right torque settings, renewing them, making sure the head and cylinder heads are cleaned properly, and that the cylinders are clean, the head gasket is the right thickness, if the head has been skimmed

The head bolts were reused. Or the head is warped. Or the torque on the head bolts are incorrect.
Some head bolts can't be reused. Because they stretch when they are torqued down. Have the head checked to be sure it's not warped. Use a torque angle meter to reinstall the head bolts.

When fitting you must replace the themostate,have the head skimmed,replace headbolts and fit a unipart headset.
Its important to flush the coolant system through after and make sure the coolant fan works.
If your engine ever overheats pull over and have it towed.
It will blow the gasket very quickly.

Did you have the head shaved before the new ones were put on?
Did you reuse the head bolts? Some heads must have new ones installed.

have the head skimed and pressure tested when its removed, if this shows nothing then you have a problem with the block face, doubtful as they are solid things or the gaskets you are using are crap.

Either the head is warped or top of motor block is warped.
