I am sure it has been discussed here before and I tried to search it but seems I am not quite forum fluent enough to find it. I have a 6cyl in my M5 and assume the sequence for tightening the head bolts must be the same for about any flathead, is that true? Or is there a special sequence for them. Also does anyone know the torque for the bolts?

I am at work, so I do not have access to my shop manual. If you do not have one, i would strongly suggest picking one up. I will post in 4 hours when I get home unless Gary Ash or Mr. Biggs beats me to it.

Here's the Champ 6 head bolt tightening sequence:

Just for comparison, here's the sequence for the Big 6:

Torque: 600-650 in-lbs for the Champ, 1000 in-lb for the Commander.

If you are going to work on your M5 (or any Stude vehicle), you need the shop manual and parts catalog. Both are available as relatively inexpensive reprints from many Stude vendors. For M trucks, the later 2R series shop manual has much better descriptions and pictures and covers many of the identical assemblies.

Does the manual really state inch pounds.????
12 inch pounds to a foot pound, so the Champ gets 55# or so and the Commander gets 83 # per bolt...

Thanks for the help! I have a repair manual coming but I hope to button this thing up before it arrives. But you know those things go, probably won't be doing that until May sometime.
Wanted to also say thanks to all of you since I joined the forum you all have been sooo generous with your help and advice, I should have been here a very long time ago! Thanks and Merry Christmas to you all

Yes, my M5 shop manual has the torque values in inch-pounds. Of course, the new, correct value for Champ cylinder heads is 73.4 Newton-meters, but I'm still calibrated in the stone-furlong-fortnight measurement system.
