...And then to get the maximum benefit of the higher lift rockers and the
performance cam, you need to raise the compression ratio (to offset the
lower cylinder pressures). If you don't believe me, read:

As far as I'm aware, roller rockers only come in 1.55 and 1.65 ratios.
Since these are both higher ratio than stock (which I believe was
around 1.46), there should be slight increase in power (due to higher
lift) when insalling roller rockers. Plus, the reduction in friction
should also theoretically increase power a bit. But the main gain will
be felt when adding a performance cam in conjunction with the roller
rockers.
