Engine protection options

[Grumpy Goat]

Both pictures look like there is some room for head covers, newer model or just deceiving?

The MaMo valve cover protectors have solid rubber inserts under them, between the tough plastic outer and the valve cover itself. That makes it stand a bit proud of the valve cover. On my bike the interference was at the bottom rear of the valve cover, IIRC. Did not feel inclined at the time to "adjust" the MaMo cover to make it fit.
