It has 14mm head studs and a cosworth "stopper" HG, but otherwise it's a standard 2.5 block. Max boost is 1.75bar, tailing off to 1.6 so not too heavily stressed.
It did 30,000 miles on 11mm studs before the HG's went, and it's now done 10,000 miles on the 14mm, but I know it's on borrowed time, and when it goes I'll have the closed-deck conversion done.
