Ditto on the personal sorting out mate. Only shit stiring on the member discount. Fully understand and appreciate the extra hours of RnD involved. Absolute legend in my books.

Update:

Things are still moving along.

The head has been scanned and a new program written to replace the previous one that was lost by the previous shop.
Some 3d screen shots of the new CAD program below.

Still some things remaining to do, but progress is being made.

I'm sure this has been addressed somewhere along the way, does the stock rocker valve covers fit the new heads that you're making?

The stock rocker covers need to be modified on the right side bolt hole location. Typically a short section of aluminum rod is welded on the rocker cover bolt hole location, and drilled to take a longer bolt. Then some clearance grinding is done inside the cover, so that the rocker doesn't hit the inside of the cover at high lift.

This is shown on Otto's photos of the right side of his engine. It looks almost the same as factory.
We may make some custom rocker covers once we get the heads back into production.

See photo below.
