Stock exhaust manifolds vs headers

Peak power (hp) or torque ? That's stock mild manner range, Stock is around 4,000 so anything above will start to increasing the powerband, 4,500-5,000 rpm is a good streetable peak hp rpm and peak torque is generally 1000-1500 rpms lower.

You have typically 500 or rpms about peak hp where power starts to drop off dramatically especially with poor flowing heads.

I was looking at hp, I had no idea that it makes peak hp that high! Generally what cam specs would be optimal for that rpm range? I'm heading to the machine shop today to talk with my machinist, so hopefully we can figure out what needs to be done to reach that 9.5:1 CR, and get a cam grind to match.
