Roush did manage to fit a MAF in one of the trumpets so I can believe a PCV return would fit somewhere.

When Mickey Lauria owned Inglese Induction Sytems, he plumbed a 289 IDF manifold with small vacuum lines from each barrel on the intake for me.
It was a very neat install.
All 8 1/16" lines where plumed to a single brass block with a AN fitting .
But after much fun of tuning them, vacuum leaks became a concern with so many fittings, I ended up plugging them and using the breathers. I had vacuum leak I thought, however. now I think it is just the complexity using their mother daughter linkage, and plain old pain in the @ of tuning webers to get any midrange out of the circuit.
