Odd question... has anyone ever looked into the possibility of running two front heads on a 2009 100ci engine? Looking at them I can't see many issues... The rear exhaust header would clear but might need a custom made fabricated aluminium bend made to fit on the rear head to make fitting the pipe easier and better looking angle. The internal oil feeds look to be in the same place (if they are the round hole). Is the oil return to the sump that curved slot? If so I could use two front barrels also... I would need to make custom throttle bodies and have a computer that could cope with two separate throttle bodies... but those small issues can all be overcome.... frame clearance is not an issue as I am planning on building my own frame for the engine... thoughts? What have I missed??? Are the valve cutaways on the pistons "handed" for inlet and exhaust valves? Then I would need a front piston also?
