Technical 21 stud v8 vacuum line

1934 21 stud v8 vacuum line goes from the dist. to intake but,intake not drilled, why and should it be?

 

My 37 21 stud also had a vacuum brake that controlled the advance. It went to a fitting in the intake. I have no idea why your intake doesn’t have one unless it’s an old aftermarket.

 

The hole for the vacuum fitting is right below your vacuum tube looks like the threads have been stripped the hole itself is pretty small and is probably plugged up

 

The manifold looks to be correct
Here is the underside vacuum hole circled in red

 

The vacuum port is marked #1
There is a second vacuum port marked #2

 

thanks everyone who responded, my eyes aren't the best,between the paint and the hole plugged up its their,w d 40 the hole maybe loosen up tomorrow
