To drill, or not to drill............. Need help!!!!

Here goes.
I had my PCV hose routed to the base of my air cleaner on my carb. I was told that was not the proper place for it and that I needed to figure out a way to properly feed it into the intake flow of air and fuel. I have an aussie head and right now my PCV is connected to the vacuum port on the intake manifold. I can't leave it there, because it will cause those two cyliners to run lean and burn up my valves.
My original thought was to drill a hole into my custom made Weber carb adapter and thread a hose fitting into it for the PCV hose. I am not too sure I want to be drillin' holes in perfectly good pieces of Aluminium, if you know what I mean. My Weber only has one vacuum port on it which is connected to the dizzy. So, I was thinking, could I run the PCV straight into the weber, through it's single vacuum port and run my dizzy and trans vacuum modulator off the intake manifold port? Please let me know if any of you see a problem with doing this. :P

if you use the manifold vac for vac advance, you will loose the advance at acceleration. that means when you open the throttle, no vacumn in the intake. the p v c hose should go to the intake right under the carb. that will spread the crank case air over all cylinders in theory. if the adaptor is thick enough, that would be the place for it.
 
A drillin we did go, a drillin we did go, hi ho a merry o', a drillin we did go!

I drilled a hole into my adapter, threaded it with a pipe thread tap and screwed in my PCV hose nipple. Once I get the carb back on the adapter I will fire it up and see what happens.

I'll keep you all posted.
