9.low x:1 compression .028 gasket
262 Lunati voodoo the shorter seat than the 268 comp should bump you DCA- maybe nm will run the numbers (or the similar duration Howard with the "15 footnote)
either gives you more lift so no need for expensive rockers and the B3 kit and you can use your current gears and converter
more duration then the 10:1 motor and spend lots of money to get the whole combination- and no real difference around town
