I guess your diesel blocks have the two oil drain oil as oppose as earlier blocks And if I m not wrong the diesel worked with small bores so might be the same water galery But with thicker wall because the bore is smaller Been trying to post a comparison between the 1.6 and H block but my bloody laptop won't post it
Agreed for the 82.5 mm From what I have been reading the 83 mm bore was doable but risky on a 1.6 block as the wall thicknerss wasn't great And For the H block safely doable but if any rebuilt was needed they had to scrap the block As it was the last boundary Once again robert collins sources ( ex drake)
