Skunk2 STAGE 2 cams are not going to give you 200whp on stock head. I would go with the Pro1s and try to get your compression to about 11.5:1 to 12.0:1. I did a 12.0:1 LS/v with stock B16 head and S2 Pro1's and it made 203whp with a ebay header and full exhaust. Make sure to get the cams degreed to match the motor.
