Revolving Intake/Exhaust Camshaft Valve

I am looking for someone to help me create a Revolving Intake/Exhaust Camshaft Valve to increase fuel efficiency. The camshaft valve needs to be made of steel and be able to function at up to 200°C. I'd like you to use your expertise to ensure that the camshaft valve meets the highest standards of quality and performance necessary for the job. If you have experience in designing and prototyping camshaft valves, I would love to hear from you and explore how your skills could help me fulfil my project's needs.
