This is a really basic question but my mind has gone blank. I have a '70 4/4 with the Kent crossflow engine. I want check the adjustment of the valves. Do I make these adjustments with the engine hot or cold. The workshop manual just says to adjust the valves to a given setting. I'd like to assume that this means cold. The same question is posed regarding the torqueing the head bolts. Hot or cold? Seems to me the head bolts should be done cold.

And contrary to what you might be told, the rule of 9 does work with that engine.
Starting with front of the engine (radiator end) you number the valves along the head, 1 to 8. If valve 3 is down and the rocker is rocking, you check the clearance on valve 6 (total = 9). And so on.
The action of re-torquing head bolts is something that is needed only with some head gaskets. Often at 500 miles from first run. Unnecessary and not a good idea to do it at other times as corrosion will often mean the tightness after redoing them is not as even as it was before!
And just so you won't believe it Ford once said to do it with the engine running! That was in an official service bulletin to its dealers, I did not believe it until I was shown it. Good way to ruin a set of feeler gauges but Ford parts departments of the day kept strips of the 2 thickness gauges involved, I tried a couple and to be honest it made no difference, having adjuster bolts without locknuts and screws helps but the whole process was just weird. Made a none sense of the rule of 9, we always joked (at BL) that Ford came up with the system as most Ford mechanics lacked a full set of fingers so no way could they count up to 9.

I have never head that the rule of 9 would not work with a X Flow.
On Series 1 LR if you had a copper composite head gasket you didn't need to re-torque the head but if you fitted the later thin steel head gasket you definitely did or you got a failure.

Don't follow this as I could well have the orders wrong, but one of the books, perhaps Haynes, used to say with valves 1 and 2 rocking, set both 7 and 8 and so on. Rule of 9 is better though and easy enough.
