Thanx for the tip.
I have just fired off an email to Cometic. I'll report back on their reply. Hopefully I will hear back soon.
My engine builder had touched base with them, but I don't think he persued a custom option.
Hank,
The outside rockers on the Harland Sharp set are already rounded off. I was looking at the inside of my valve cover and thought that even with a spacer it might be an interference fit.
I did notice that Tom Lowe has a tall cover available. I'll get in touch with him to get some feedback.
Cheers,
Paul
