So you think it's all about the base circle of the cam??? You have lots to learn my friend. There's more to the valve train than a spring and a base circle..
Here's a problem as well, you put those springs in your customers car and it wipes a lobe a week later. He takes it to another shop and they find the increased seat and open pressure, who do you think is going to be paying the bill to repair it ( whole engine strip and clean) as well as set the springs correctly??? Yeah, it's going to be you. Try arguing your "base circle don't much care" spring theory with the customer on that one..
