FP should be set @ 39psi vac line off. timing should be around 10-14* spout out. 10* is the factory setting. you can up it up if you'd like for performance but know you may need to run premium fuel to do this. $$

for rwhp? hard to say...maybe 270-290. not too sure about the heads performance but that cam is pretty lame.

That cam should make decent power IMO, but I think that intake is pretty lame. But I agree fuel pressure @ 39psi and timing @14*.

The system max isn't that bad of an intake but I wouldn't have chose it. Like already said 39psi no vac and 10-14 for timing. you can probably bump up the pressure some once you get it going and maybe a little more timing if you use higher octane gas.
