still plugging away, the chambers are done, hand deshroud, intake guides milled down about .200, exhaust about .030. Exhaust bowl blended, still need to work around the guide boss and profile the roof hump. How much can I knock down the hump?? I’m thinking only around .010 to .020 after knocking out the old core plugs and taking a peek.
