I am seriously looking at Crower Stage II cams with titanium retainers and springs. Since Turbo is already off the drawing board due to budget I am planning this as soon as I get my bonus this month. I just need some technical questions to find out how much whp gain can I get from this setup. Also, if there is anybody here with any recommendation will be greatly appreciated.

Crower Stage II cams

Titanium retainers/springs

Spoon thinner head gasket (I'd like to know if anybody has experience w/ this) To bump up the compression a bit to compliment the cams (Is this advisable)

68 mm throttle body

B&M fuel pressure regulator

I already have the following

AEM CAI

DC 4-2-1 ceramic headers

Crane HI6 ignition

NGK plug wires

Apexi Dunk catback exhaust

Other options I am looking at besides what I have and what I intend to buy

VAFC w/ dyno tuning

Skunk2 intake manifold w/ shorter runners.
