The work that my CIS buddy did with setups included the HFS and fuel head mod.
What was found was that the K27S worked best with the Euro head and the HFS worked best with the modded head on that particular engine. The power level cutoff for the fuel head mod was 375whp (< 375 S, >375 HFS) and was independant of the choice of turbo.
