Wow - that's nice work Lippy. Shouldn't show too many pictures of those as you will start getting inquiries to produce them. FWIW - I think studs are the way to go, especially with an aluminum block. Do they have an allen screw recess or screw driver slot to help tighten them? I can't see what a little blue locktite would hurt to keep them tight to the block. But then the tensioning by the nut is taken up in the stud and there's less risk of galling and stressing the block threads by the combined action of tensioning and friction when tightening everything down. Maybe an ME can address that better than this aging CE.
