I think you could use a little more than the xe262 with your 4 speed and 4.10 gears.
I'm currently running a Lunati with 230@50 duration and .480 lift. it will work with stock rockers and give good power to about 6000.
A set of KB107 pistons should give you 9:1 or a little better. Should put you in the 14's easy. When do you plan to do your build?
