Being somewhat new to Stovebolts one thing I've learned is how the cylinder head is the biggest obstacle to these powerplants obtaining the coveted 1hp per cubic inch plateau.
In developing an aluminum head could it be designed to increase it's efficiency while still maintaining reuse of as much of the existing hardware?
Or perhaps use a more modern rocker arm and manifold assembly such as whats on the later inline 6's & SBC's?
Just throwing it out.
