All the edges have been smoothed out.
Tom is double checking everything and leak checking the head's newly cut valve seats.
All the numbers are checking out! The seats hold pressure.
My freshly rebuilt SR20 head is finally ready to take back to the MotoIQ HQ to install the valves! At our HQ, Howard Watanabe will blend the ends of the Newen cuts into the port and the chamber to give my head nearly the same flow gains as a fully ported head.
A big thank you to Tom Fujita for the awesome head work on my SR20. The valve job will give me just enough extra reliable power, which is ideal for a drift car. A valve job is one of the easiest and most efficient ways to make some more power without throwing any extra parts at your engine. Stay tuned as we continue on this SR20DET drift engine build!

This is another project that vanished I wish we could see again
Questions!, who made the valves or how were the valves made for the newen cut seats?
did you read the article at all?
