I have a 390 with the Erson roller rockers and had the same problem as yourself with too much oil to the topend when using 0.090" restrictors. The 0.090" restrictors were allowing oil to flood the heads up to the pushrod holes. I've since reduced the restrictor size to 0.062" and while it decreased the amount of oil considerably, there's still a lot of oil up there when the engine is held at 3000 rpms for any length of time.
