Chuck, as far as I know, the head and all the necessary parts are all up there.
It's all up to Chumma's schedule.

I estimate it should be about like a Norton Manx.

Congrats, Chuck, and the Ace team too!

I  have a short video of the rockers actually running on the engine with the lids off, but I haven't figured out how to post it here yet. I will try again this afternoon.

Fireball #2 running with world's first Ace GP Head with high ratio roller rockers and high port in action in the real world!!!!!
Just a very short video showing the running engine with the tops open to view it. It's not an "on the road" video, but that will come later.
 

Yours will be like this soon too, Chuck! We are currently working out the various kinks with Rod's Fireball.

Is this working for anyone?

Works for me, looks and sounds sweet!
In the flesh, how do these roller rockers sound compared to out sewing machine tappets?

I think it's probably about the same sound. Maybe some minor differences, but it isn't intended to be quiet.There's actually more lash in these than in the stock rockers.

BTW, that's .510" valve lift that you're seeing there, and it's flowing over 230cfm at peak lift.

any new news on this GP Head?

[Guaire]

Sounds like a gun.

[ace.cafe]

Yes, we are still playing around with pushrod lengths. The bike is running and riding around. Giving very good power, with a good surge at around 4k rpm, and really going strong at over 5k rpm.

When he is finished and makes a video of the finished result, we will post it.
