Still low vaccum

[Stealthfxxr]

Got new cam installed and broken in and still got low vaccum at idle bout 5in. Could it be a head gasket?

Does your reading bounce around alot or is it fairly steady?

Rock solid at idle 5inches.

That's just way to low, like there's a "metering valve" or something on that line,,, have you tried a different vac source?
