Typical vacuum readings for 218/218 flat tappet cam?

[YGETV8]

I'm getting about 12 inches at an 800 rpm idle, or so. How does this compare? Thanks,

Sounds Puuurfect. I get as low as 10 on a hot hot day

Cool... thanks for the replies. I had no idea if that was okay or not. This car still has a very rough cold idle, but not too bad at all once it hits closed loop. Symptoms sound like a vacuum leak to me, but I'll be damned if I can find it! Thanks, Jay
