WF:
You need to talk to your machinist. Really. Anything on here is speculation. Maybe he did use a set of springs that allow you to run the cam you want. I don't know what you have. I know you know of the NastyZ post since you quoted it. I also know it's a huge thread that's tough to read through in its entirity. But at least get very familiar with the first 3-5 pages of it.
Anyway, If you DO need to do the modification the heads need to come off.
Read this, but remember it may be a few years old and there may be new parts out that make it easier:
