Springs?

At what point does it become necessary to use after market or dual springs in a D16z6 head. I'm trying to reach a goal of about 300-325 hp. Any input is appreciated.

mostly you would use them with a big lift cam where the factory coils would bind or if your looking to up the rev limit

Stock head is more than adequate at 325 whp.

Sounds good. I'm having it ported and polished by a local machinist. I am probably going to run a slightly more aggressive cam but I'm sure what to get yet.
