That's a pretty neat trick getting the earlier iron liners to fit the later block, especially since the iron liners are smaller than the holes!
As I read your post I can't help but wonder exactly what mode of failure you have experienced or feel you need to guard against?
The #1 problem I've experienced is the mains getting warped and cutting off oil supply to the rod bearings. Is your S4 'zeus' casting not rigid enough to eliminate this problem? What is your target HP output and rev range?
