In my experience, almost every customer asks for more power than they are actually willing to live with!
I’d agree with that.
I guess I was a bit of an odd ball (again) when I called up asking for torque instead of power and had a vacuum number in mind.
As for the heads, the numbers you got are about what I expected.
The heads are still a sticking point in my mind. I kinda backed myself into a corner with the pistons. Better heads would likely wake up the 541 nicely but the smaller ports I've got might make it feel a bit more responsive on the street. Just what a 5300 lb cruiser needs.
