I would definitely recommend using the Isky tools for flycutting and using a head with the seat cut out of it. I wouldn't recommend cutting your pistons with sanding wheels and using a wrench for a depth measurement! :roll: Your valve reliefs need to be larger than the valve and you need to know how deep you a cutting the relief into the piston. I'll see if I can find you a link of the correct way to cut reliefs. Kevin Doe had a nice thread on it but the pics no longer work.
Something like this needs to be done with the proper tools. Making that kind of numbers is not cheap. Do it right and ensure you won't have any headaches down the road.

Actually, we don't sell or rent any flycutting tools. If we did, I would have told him to give us a call and we'll get him fixed up. I don't think there was anything ignorant about my post. IMO, for someone looking for the kind of power the OP is looking at, it is worth the money to purchase/rent the correct tools for the job. It's not a cheap build to make 500 to the ground. I would hope he has the money to do it correctly if he is really trying for that kind of number.
I'm very aware that this process worked for you. However, I think using the proper tools eliminates several variables. For someone inexperienced in flycutting, I would always recommend the proper procedures rather than using a pieced together method. I'm sorry that offends you. It wasn't meant to.
