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?

1979 Hurst/Olds W-30 - whit and gold
1964 Volvo PV544 - desert sand
1961 Willys Jeep Utility Wagon - saturn yellow

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.

Still moving forward.
 :)

Now looking at possible production of compatible rocker covers which eliminate need to mod the stock covers.

A few of the latest pics below.

Next week starts a test billet machining which we expect to be okay. Want to be sure it comes out as expected, and sort out any issues, if any arise. They say they can complete it in a month or thereabouts. We already have cleaned up a few spots that needed to be addressed from the earlier versions, and included those in the program.

After that happens and some on-bike tests for fit and stuff again, we will go to production.
 :)


Hopefully, the 3rd time will be the charm.

The Fireball 3 has arrived.
  The GT is already light: wheels, spokes, frame and suspension. Increasing the power is magnified on this bike with an excellent power to weight ratio. Power to weight is the Ace card. Putting the power of a 500 - 600 lb bike on a 400 lb bike, changes everything. You can't buy this experience at any dealership. [Of course you could if RE would adopt a factory version of the Fireball!]

  Next step will be finishing and final set up. That means valve seats, guides, valves, springs, tappets, rocker arms and oiling spigots. The factory job is alright, unless you want to wipe out the reviewers mantra, 'needs power'. ACE fixed everything the factory didn't, so we can say, "POWER".
  Later this week our set up mechanic/tech will start on his shift of the Fireball job.
 
  A few years ago, when I was at his shop he helped me a lot. That is, the velocity stack was on the hook in the retail area. He told me the stock coil is a 'usual suspect'. ACE Motors will sell you and anyone, the same DynaTek coil set up as used on the Fireball GTs. Simply, "There's a sound to power. And it's LOUD!"
 
  The Fireball is coming.
