themselves rather than connected to a cylinder head. At least, to confirm previous flowtest results of the MS manifolds.. Here's what I got: 
Here's how I connected the manifolds: (Abeler manifolds shown here)
 Only one port was flowtested at a time. I fabricated some blockoff plates for the inlets to allow two ports to be blocked off at a time to test each runner independently. It is hard to say which test procedure is the most effective to use though. The way you tested them shows how the manifolds being tested flow on that particular head and not all head configurations are going to be the same. Whereas the test procedure I used is flow testing just the manifolds themselves. Each procedure has its benefits as well as drawbacks - I just prefer testing the manifold itself as it is easier to reproduce the test conditions and the data collected is illustrating how the manifold itself flows rather than a combination of various parts...... Good work though - thanks for taking the time to do this! :)
