[SEL] Hercules update, now Herc XK's

[Curt Holland]

Bill, Tom,
Any thoughts as to what the holes were for on the XK's? Was this to 
support rammed molds? Something for shrinkage?
Was it advances in casting technology that allowed the elimination of 
the holes on the  JK's?
Would be some good history to know....
