Valve comparison on the flowbench

[SappySE107]

We used to have copies of the OEM valves available, but these days they are all based on a different design for some reason, which hurts flow. I was able to modify this one to be back to stock so its not hopeless, but needs to be addressed if you want to keep performance. Based on a stock 3500 head. Supporting wot-tech is greatly appreciated.

Testing intakes now Bit more work though since the 3400 vs 3500 port design is significant. Need to check both with the same valve work.
