Response to I am lucky I guess, i have three sets of C4s that are almost perfect
Would be nice to have actual flow charts on both style heads
so you can see the flow difference in the lower opening rates
the C8s may flow better at lower lift rates than the C4s
The C4 exhaust port at the end has a lip on the wall that would disrupt flow.
the C8 has no lip and smooth wall just like the med riser head.
