Milwaukee Eight Cylinder Heads

Hard to tell from the picture, are those four different size valves?
Would be nice if they were. Any flow or spec info out on them yet?

They do look different sizes

Anyone know the valve sizes, stem diameter, spring sizes,etc?
In the pictures they look like the 7mm stem sportster valves and springs.

Intake valves are 39.8mm and Exhaust valves are 32mm.

Stem diameter and spring sizes I don't know.

Thanks
Those are not as big as Vrod performance valves.

I have the stock sizes on file, I am wondering if the change valves and stagger sizes when they cnc the heads.

What's the part number of this new kit or of just the CNC heads?

Valves are not different sizes from each other.  The Instruction sheet shows 4 intake valves and 4 exhaust valves but no info on their part numbers yet.

64 MM t/b hope it tunes better than the other SE version. Not a huge fan of the hurricane T/B , new 5.5  how its a fan and not a stream unit again like the Hurricane

Interesting how they changed the rocker ratio...

M8 on a Sportster ?  That could be interesting.
