[Question] Vacuum pump set up help

Did a leak down test on the motor. I'm good there..Where is the best place to hook up a vac gauge for testing the vacuum pump system? Looking to set up my regulator to 8-10".

I've seen a 1/4" fitting welded onto valve covers or to the base of the intake on other deals. Is the the only way to get a gauge on it?

Thanks
