not an NA honda guy anymore, but I used to be.

1) Are OEM cams (not including type r) better than aftermaket cams in that setup?

Chances are NO, with higher CR, you'll see better power w/ aftermarket

2) When building an N/A motor, are "aftermarket" cams important? If so, why?
Yes, more airflow.

3) Do you believe "aftermaket" cams are a "waste of money" in a N/A motor?

Depends on what's done to it.

4) What aftermarket part do you believe is the best bang for your buck (power wise) when building your N/A motor?

Higher CR pistons AND cams, as a package.

5) What is the point of raising your rev limiter (maybe about 1k) with stock cams? (if there isnt a reason, post that)
there isn't any, the stock cams already start to run out of power at the very top end on a stock rev limit
6) Does increasing displacement only gain torque, or does it increase torque and horsepower?

If you gain torque, you're going to gain horsepower, that's how it works.

7) Which motor "should" put out more power, a non-built b16 with bolt-ons or built ls/vtec with bolt-ons and stock cams. (this should be a easy one )
LS/V, no doubt

LAST QUESTION!

8) A person with a built bottom end, N/A motor who think cams are a waste of money is a noob and should DIAF, YES or NO?
YES. FFS, how stupid is this person.
