I had the opportunity to ride with Kevin & Jenny Prus at the Ohio Model T Jamboree in Perrysburg, Ohio. I could not help but notice how smooth the engine ran. Kevin said he had designed a high compression head that allows 8 to 1 compression. During the tour which cover hills, flat ground and country roads the car preformed flawlessly. I visited Kevin at his shop and he showed me the Prus head. The workmanship is first class and the head is well designed.
If your interested in additional information you can reach Keven at 330-774-7130.
I took pictures but they are to large for the Forum. I will try and post them on Facebook.
