rotor heads

[fasttalker83]

Probably another stupid question but can you stick a 14mm head on an old pump that had a 12mm rotory on it have I have a 90 D350 with a 12mm rotor and would like to see if I could pick up a 14mm to give it more hp if this would help Thanks

you can but with the 14mm head you will also need a larger set of sticks, a very good fuel supply system with larger lines larger pump larger filter housing, and alot more airflow to use all of that extra fuel.
