I assume you used 1:1 rockers because you have a performance cam?

Most cams are designed to be used with a specific range of rocker ratio. Some are designed for 1.0 or 1.1/1 and can be spiced up with 1.25 ratio. Some are designed for 1.4/1.5 ratio.

Pat is a VERY smart man, and I'd love to know more about his head program. You know: intake runner volume, flow rate, chamber size and shape, etc. I'll bet Pat has more knowledge of aircooled type1 engines than anyone else these days.

The compression, displacement, rod ratio, cam, rockers, compression ratio, basically everything from the velocity stacks to the exhaust outlet all matters to work together.
