We have large intake ports so I thought a turbulence generator could help:

Nowadays nobody mentions this type of equipment that made a world of difference when Angel Nieto introduced it in the 70's.
My standard a/c backplate has the rounded intake "lip" truncated compared to yours, so it's well adapted to operate up to 6,000 RPM. To remain legal, we are only offered V&H Monster Ovals; in this case I would have a bit less torque in the low end but able to burn more fuel in the higher revs due to the two identical pipes that provide less back pressure than the original ones. Cruising at low speed with the new exhaust changeover valve is quite pleasant for older people

Have you done the change yourself and kept the original pushrods? The local HD technician told me to remain under 100HP to play safe.

True, and the most sophisticated means of law enforcement as well 
If you appreciate to live in an area that has one town every 5 miles with 30mph speed limit, 20mph in the city center, 40mph in the outskirts, potholes with sand and loose gravel in spring, hysteric and saturated traffic in the summer, bone freezing temperature during 5 long foggy months of the winter season... Then yes we are lucky to live here.
I enjoy YOUR roads better, perhaps because part of my family still lives in BC, Victoria included
