Mines reads 17 at idle with stock cams and an Autometer guage.

Im pretty sure around 20 is good. mine reads at 20 with an autometer.

20 is good for stock cams. I was holding 21-22 on stock cams.. on my 264/272 combo i was as low as 10'ish and have now degreed them and gotten back to exactly 20, so a lot of it depends on if the cams have been degreed or moved (or if the timing belt instlall left you with one gea off a tooth)

I get about 18ish....but I have a leak in my brake booster when I press in on the brake so... it varies. ;P
