I need help ;-)

--- Quote from: "Range Rover Blues" ---It's a small square lug, obviously on the finished surface of the head, less than an inch square with a hole in the front (or rear) face. You should be able to see it in-situ on the driver's side head, though not get the callipers on it to measure.

I doubt you'd really tell much if you can't measure it... even then you would need to be very accurate with the measuring.
What you could do is get the old head off...
Measure the volume, and meaure the volume of the new head...
If they are the same, just bolt the new head on... if different skim the new head to match. Unless the new head is already skimmed too far.

I just knew this would not be a ten min job. Thanks everyone for the help so far. Sorry if sound thick just never done this sort of job before. changed heads on old cast blocks (talbot sunbeams etc). just not had any experance with alloy heads and dont fancy having to do it twice when i muck it up the first time. :wink: :roll:

Do you need the Disco everyday???
The other option, is to keep your existing head.
If you can get the head off and over to me, I can get it repaired at work.
Means you can keep your existing head and not worry about CR problems etc etc.
Regards

I'd be very tempted to take that offer up, provided you get the head off without it twisting then put it back as you found it. Trust me, if the first time you do the job it all goes relatively smoothly, you'll not think twice about tackling it again some time.

I think you need to explain how we would go about this though. One of the problems with measuring the combustion chamber in the head is that the head is often skimmed because it has warped, so it can be skimmed more at the ends than in the middle (they even get made this way) so whilst it's very accurate (provided you are dilegent in the measuring) because you can work out exact figures for each cylinder, the information alone isn't always enough.
