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.

Jon don't knock it off unless you've tried it, it works really well

Here is another thread with "proper" tools (sticky)

Or just use the Lindy tool and you don't have to cut out any valve seats. Do a search for "lindy tool" and "flycut" and you'll find what you need. It worked great on my build.

Of course you would, and I would bet you either rent or sell those tools as well. Not everyone is rolling in cash and my method works damn well for what it is. Don't make ignorant comments about the fact that we used a wrench for measurement, it was mic'ed at .080 thick and gave us easy, repeatable results on every valve. And yes, the valve guide height was checked and within .002 across the board. Everything was measured multiple times and every valve relief was hand finished so there would be no issues down the road. It was not a half assed, backwoods modification. Hot rodding came from normal people like me making things work with what they had, so please don't act like there's only one way to skin a cat here.

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.

Agree, the Lindy IHPC is the best flycutting tool.
