1) You don't 347cu/2 =173.5
6000rpm/1728=3.47 173.5 x 3.47 =602
Assuming your motor is running at 100% thermal efficiency.

2)??? Don't know!!
3)I run Edelbrock heads at 11.5 :1 on pump gas
4)??
5)I would go for the flattop and chamber.It leaves a lot more for the builder to actually shape or flow etc.
