• SHould I shave a brand new 1.9 head to give it the same or close to the same CR as I had with my 1.6TD? any idea on the specs of this?
  
  Thanks

• I really don't think you can gain much by shaving it as most of the volume is in the pre-chamber.

• no.  you should have plenty of compression. the 1.9 head does reduce compression, but its not as bad as people act like it is.  malone daily drove his with out issues, just a little bit of white smoke on start up nothing major, and he had lower compression than just a regular 1.6/1.9
