The V8 Owners Forum -

hello chaps i am looking for the head bolt settings for my landrover 3.9 on a m reg she has the 10 bolt heads on it but i dont know if there same as a normal 14 bolt any info be cool i think its weird to as its got 10bolt heads on a 14 bolt block could they be 4.0 or 4.6 heads??? please help thanks

Hello v8man1,

All heads made after 1994 had 10 bolt retention, and essentially all heads for 3.9, 4.0, 4.2 and 4.6 after that date are identical.

Using 10 bolt heads on 14 bolt blocks was am I advised quite normal for Rover to do. The 10 bolt heads have smaller combustion chambers, so composite gaskets would be used.

The heads will have been retained with "one time use only" stretch bolts.
You will need to purchase a new set, which I believe will come with full fitting instructions, which must be adhered to without exception.

hello rom mate thanks for the reply thats really helpful,, do u think i get away with putting the stardard head bolts on the old girl?? or just get the 1 time only ones do you know how much they are by any chance thanks again

Justin,

You can use either the one time use only stretch bolts, or high tensile bolts which can be used as often as you choose.

I am not sure of the cost or the best place for you to purchase, as I don't live in the U.K.

Do check your other post regarding your headgasket and coolant loss.
I posted a response.

thats cool mate thanks for your help thanku

you may want to fit ARP studs, if you think you will need to take the heads off again.

They are about £100 though
