It's prob worth getting the first three digits of the engine numbers as there are different types of 3.5, different compression ratios, later
blocks were stronger (known as stiff blocks cos they had wider ribs in the v valley). There are plenty of websites on google that will decode the
block number for you.
Cheers

Blocks after around 77 were stiff, so anything out of a later RR or Disco will be fine in that respect.
Look on the block down by the dipstick, there is a machined flat with engine number and comp ratio stamped. You want to see 9.35.

hmmm, not sure that is correct.
All rover v8 heads are aluminium alloy so will have inserts.
But the early heads are not suitable for unleaded, these being fitted to P5B, P6, MGB V8 and early Range rover.
The heads you have a ok to use with unleaded.
