Please help with vacuum pressure test

Hi Guys,
My motor is running fine as far as I can tell, but I want to make sure that I have it tuned properly.

I running a Ford Crate ( specs below ) that has 4k on it.
No changes have been made by me. Timing set at 10 deg.

Carb is a holley 770 cfm street avenger. No changes from factory settings.

From my limited knowledge it seems that the timing may need to be advanced a few degrees.
What do y'all think.
thanks,
Roger
