Nor do I want to start a tread about accurate dyno's but when I see your inlet valve so deep sunken into the head, I guess it was not when you where measuring the power of 190 Bhp?
But max power does not matter, I had and engine with 193 Bhp and several with 190 Bhp and my Grandma can still use the car for shopping. It's idles like normal, it still pull's very well from 1000 RPM and all comes into action before you see 3000 RPM. That's what I call a good engine.
Indeed with the cam time like in you drawing you will see a peak of power very high but takes a lot of time to get there. Really with a bit of work you can make this engine a lot better. Put some new seats in the head, get the geometric as good as you can and will already be a lot better.
