I was in the same fix as you. I did drill a hole where the OEM pvc hole was. I did this by cutting the fins slightly larger than the hole for the pcv valve on a Bridgeport. As you said there is no baffle anywhere for the pcv so I made one from a short piece of thin walled sst tube with an o.d slightly larger than the i.d of the valve for a press fit. I drilled several 1/4" holes at the bottom of the tube, then cut it so when pushed through the rubber grommet it sits on the top of the head between the rockers and the pvc valve sits in the grommet in its correct position. Without the baffle it WILL suck oil out.
