[BUCKEYE COBRA]

I'm looking to bump up the power in my '87 302 truck block based BDR. It currently is stock with a Air Gap Rpm manifold and 625 Demon Carb.
From what I seen and read, I'm sold on the AFR 165 heads my application. Still debating as to the stud vs pedestal heads (see earlier tread).
The pedestal heads would let me get started without new rocker arms ( could add at a later time if needed).
Debating just doing heads now and cam later or all at once.
Has any one added the AFRs without a cam change?
Can I do a cam upgrade later without removing the heads?
As I am not looking for a 6k + motor, will I be OK with the factory rockers (non-roller)?
Thanks for the input (again).
