If you have a stock B20B 9.6:1 compression engine (with or without a P8R head... you were not clear) and Crower 62405 cams, you will NOT get to 190 wheel HP, nor will you be able to make power at (or even near) 8500 RPM. This is really way too much camshaft for a moderate compression engine. Also, your cam gear settings are crazy odd... you need to DEGREE them and stop guessing... those settings are creating WAY too much overlap and might cause valve-to-valve or valve-to-piston contact.
