All lines of heads are designed and developed by Speier Racing Heads.  Our main goal during the development process was to design heads that would simply out perform the competition.  Velocity profiling, port shape, and cfm, are keys to making power.  Great care and focus has a set of cylinder heads from Speier Racing Heads a smart and logical choice!

This is my 227cc offering.  It is based off the USA Pro-Filer core and features 2.08-2.100/1.600 valves.
