Jon Suggested that Mig Welding tips would screw into the intake manifolds. Does anyone have any additional suggestions as to where one may source nipples to attach a homemade vaccuum balancer to the intake manifold?

OK, did some research. The thead is supposed to be M5 x .8.

You can pick up some M5 x .8 allen bolts and drill a hole down thru the center to make some nipples. Put some grease on the outside to make a seal so you get good vacuum.

EUREKA!!!!

Wow Jon! That's 5 options in less than 24 hours. If only I could get that level of service from the dealer. I'd say you've gone above and beyond the call of duty. I was going to swing by a welding shop today and check out the mig tips but It was easier just to click and pay. Thanks again! Your help is much appreciated!
