I took one before measurement and have calculated a flow improvement of almost 40%.

My current calculated flows of >255 CFM @ 25" vacuum and 0.45" valve lift are also very respectable.

Compared to other numbers I have looked at thats about as good as it gets for head with 49mm intake valves.

The CFM numbers may vary depending on the equipment used and what is used to guide the flow into the port but this whole experiment was all about making sure the head flows were evenly matched.

I am happy to report that all the heads except one are within 1% of each other, and one is about 1.5% off from the rest.

I will be looking to see what is different about my oddball so I can try to correct it.
