I recently completed a 6.5 build for a customer that requested it be strong, so we decided to go the route of splayed main caps and head studs. All components were magged, pressure tested, measured, machined, cleaned, measured again and cleaned again. Theses are all regular procedures when building an engine but when splayed caps are involved the block recieves additional work to allow the splay caps to fit. The original outer bolt holes of the three center main saddles have to be filled with threaded stock then cut off flush. Next the main saddle rails have to be machined down to allow the wider caps to fit. Then the new outer bolt holes have to be drilled and tapped at the correct angle for the new caps. Finally, the main saddle bores have to be align honed. Here are a few pictures of the build along the way.
