Trouble is the head expands at different rate to the block and causes them to come loose and if you torque up higher they can and will crack the block.
Hence why the cosworth and ford designers opted for the stretch bolts.
Or the other option is long studs but only on a 200 block.
Interesting and I trust if that you say you checked then there must be a problem...I know there are lots of posts. When we took the cover off my old Engine we saw ARP written on the studs...do not know the spec but as far as I know it was ok for 15+ years
