I am going to be running a 92 351w block bored 30 over with stock crank, stock rods, and forged pistons. It is going to have 9.5:1 compression and i have a set of gt40p's with over sized valves. What ratio roller rockers am I going to want to run, 1.6 or 1.7 roller rockers? Cam and springs are going to be based on this decision

You should really select a cam before you select rocker ratio. Seems like backwards thinking to do it the other way. It would be a good idea to talk to your cam supplier about what route to take on springs and rockers.
