1) yes, god I hope it doesn't rain (see avitar)
2) three years ago? maybe more?
3) no coolant in da oil
4) compression is between 120 ish and 130. Could have been my fault for readings though, had never done it before and wasn't sure of the correct proceedure.
5) yes, but it doesn't seem to have effected anything
6) ? I love my Disco, but I'd like an '04...
7) what are we talkin' $500 U.S.D.? There's a place close by that will level the heads. But if I include a valve job, it will go UP! Maybe $1000 total? Sure beats $400 car payment for 3/4 yrs.

The big thing with heads is not taking them off, it is putting them back properly. The place they usually leak is simply from the front and rear water galleries. If you use coolant, you will tell if they are leaking by a white power left on the block after the water evaporates.
The problem with putting them back together is that with changes in the head bolt threads in the block over the years, it is difficult to get the correct tension. This means that even if you use a torque wrench, it will not tighten down properly. Within a relayively short time it will start leaking again.
So if you are going to do it, go and buy a set of ARP head studs to replace the head bolts. This will get the head tension correct as you are tensioning with steal thread to steel thread, rather than steel thread to alloy. ARP may not have anything listed under Rover V8, but they have them listed under the old Buick V8 on which the Rover motor was based.
