Generally most folks should get at least the following (brands chosen based on what we used, others are likely just fine):

GSC valve springs
Reimax oil pump gear
Manley or Carrillo rods
CP or JE pistons
ARP head studs

Those are the mid range in terms of price, and will easily hold 600 whp.

If you plan on 9,000 RPM the the carillo rods with CARR bolts are the way to go, above 600 whp we may put in the stronger wrist pins, and the standard ARPs may not be enough to hold 35+ psi long term.

Anything above this basic build list will jack up the price significantly, and you will likely be no longer using an OEM gearbox and not driving the car on the street. Hooking up over 500 whp on streetable tires is a challenge below 80 MPH.

Spinning to 9,000 is also not something we would recommend. Though you can put enough valve spring in there, cams that make power that high will make terrible power down low, and using rockers the chance of failure is exponentially higher once you go past 8,000 RPM. Can you do it? Sure, but for how long....

But price wise a lot of this depends on your motor starting off. If it is in good shape then just basic machining to deck the blocks and heads is all you need, along with a quick hone. If there is scoring or the cases are shot, then you can expect to add 500-1200 to the cost. If the heads are high mileage then it costs a bit more to change out all the guides and seals.

Could you expand on what you mean by "but to properly assemble a long block takes much more work and there is a lot to potentially mess up"?
