I am curious about something. That is the number of head bolts/studs on 
flathead engines.  I had an old car once that had a Continental 6 cyl 
and that sucker had about a million head bolts. Same with old Ford 
flatheads, lots of bolts or studs. And yet, with todays high compresion 
engines, greater dimensional tolerance requirements for flatnes, etc, 
most only have 10 bolts/studs for each bank of cyliners.  What's up with 
all the bolts on a low comp enigine?
