Given the design you're attempting to achieve, your valves would have to operate in a completely different manner, so as to prevent the loss of gasses back into the head/oil containing areas, and to prevent the presence of mechanical parts in the (very hot) exhaust stream. |
Could do it for the intakes- no hot gasses- if the gains are worth it. Or... if it can be done.
