Disco 2 Stainless Brake Caliper bolts - Big No-No?

Was just looking at a cylinder head and don't really see how these bolt it down, looks more like they are just sort of holding a top section on or something

Quite right. They are attaching the rocker cover, which would explain why they are 8.8 bolts.

I'm neither familiar with the Td5, but I seem to recall there is a "sandwiched" alloy section between the cam cover and the head. Probably holds the cam, @jamesmartin is the guy for what's what and he would know for sure.
The photo I looked at made the bolts look like head bolts, I still wouldn't use stainless A2-70 bolts on anything other than pure "cosmetic" light/medium type work, just because when you tigten them up a bit too tight, they break, but you already know that.
Normal standard High tensile carbon steel bolts are 8.8 grade, so in that spot that is ok, head bolts will be higher grade, other cad plated bolts in steel are usually 4.4 grade or if Chinese made about the same strength as chewing gum.

I thought they would be head bolts too. I have serviced Td5, but never even taken the plastic cover off the top. They are where head bolts would be on many engines.
Yes, James would know every nut and bolt on it!

Like I said, I'm so far in the past as far as Landies go, just getting up to speed on 300tdi, only ever just had a peek under the bonnet of a couple of mates Td5 powered units, (enough to know I don't want to own one). Think I'll stay with my 300tdi powered D1, when I bought it about 7 or 8 years ago I said it would last me the rest of my driving career, unless I win Lotto, then I'll buy a brand new...........wait for it......purists look away now .......EVOQUE, just because the boss lady likes them! But then she likes any vehicle that's 1/ a 4wd , 2/doesn't need me to work on it constantly and that 3/ has an good airconditioner. The D1 meets two of those criteria, guess which one it falls down on, but then, it keeps me out of the pub.

Hoping to get out of cars altogether soon, except for maybe the odd hire. Boats are the future, for me at any rate. And probably for everyone else if the predicted sea level rises take place.

Few floats round the disco and a propeller on the rear diff and should be fine, bet the water will still make it in through the sunroof though

In reality my next vehicle will be all electric, but not until we move full time to our city abode, (don't mention how the electricity is generated to charge the batteries).
Hope you're including an electric motor for the canal boat then, that will complete the circle, and you'll be keeping yer feet dry.
