DIY Vacuum Flow Testing Cylinder Heads On The 351 Cleveland 2V Heads

Well, it is what it is in this rudimentary cylinder head flow test, using vacuum to check flow rate. The jury is out on this method, but it's time to step up and use a more accurate device to give us a clearer A/B comparison, between ported and un-ported Aussie 302 2V cylinder heads. I've found something that can give us a more straight forward cylinder head figure.
My next video will be testing the cylinder heads with this new device.
