Hi Frank, The re-worked head is a tried and tested Thunderbike development which restructures the internal port routing, shapes and dimensions, flows them in the appropriate manner and then finally the valves are refaced, the seats cut to a 3 angle profile of our choice and the compression increased by machining of the gasket surface to our specification.
And yes it perfectly ok to ask, thanks for your question.
