1500 Cylinder head

["Ken C" <sdspitfire@worldnet.att.net>]

Spitlisters,

I have read or heard that the USA 1500cc cylinder head is 'deeper', and,
along with dished pistons, typically yields 7.5 to 1 compression. If flat
top pistons were used, any idea how much the head have to be milled in order
to bring everything up to 9.0 to 1 ? Would shorter push rods be needed ?
