I have the tools for fly-cutting but they were made in the LS3 valve sizes since I did my top end. I can dig them up if you're interested. I got mine from Lindy Tools, supposedly the best company for them. Mine have the optional stopper also, makes it super easy, just set the depth for cutting and it'll stop after you reach it.
My intake cutter was used for the 8 cylinders once, exhaust cutter was never touched.
