Talking of JFab, he makes a superb head steady. I think it would be far easier to have a similar bracket made for the front which picks up on the cylinder head studs. Then just a boss welded to the down tube and job done.
No guarantee, but surely a help.

Like this?

brooksie:
Bingo! What would make it a little nicer would be to have the steel compress against the aluminium. Then only an aluminium boss would need to be welded to the frame instead of that bracket. Less chance of fatigue as well. It would make it "less busy" in that area and aid getting the motor in and out prividing a little more room.
As it is, I don`t see enought clearance to get the head on if the bracket was welded to the frame as it is.
In any case, I`m going to have to do something like this before I ride mine. I`m just not going to have any piece of mind otherwise. The originator of this thread was extremely lucky to come away with just a scratch and a bruise. He must bounce well!

sandblaster:
There is room to remove the head.
I'll demonstrate when I'm a bit further along.

brooksie:
Personally, Id still prefer the steel squeezing the ali. Do you have a computer file for the plate...
What material have you used...

sandblaster:
I designed one just in case they were no longer available.
But, they are still for sale:
