I think what Dimitri is saying that because the p76 block has higher cylinder banks than the rover there is greater leverage applied from any stresses applied to the block at the deck, from say expansion/contraction, mechanical stresses from the actual working of the engine...etc. This is what causes a specific problem with p76 blocks
I take your point about the differences in expansion between the engine block and any bits welded on it.
Apart from the higher banks there is no difference between the normal rover blocks and the p76 in terms of the tappet area which is generally not a problem with these engines as far as I know, So I think what Dimitri wants to do is reinforce the actual cylinder banks which is what causes the initial problem with the p76 blocks rather than the small structures in the tappet area.
I will not have myself summarized better
