I have Turks clutch recommendations parts ready to go in but not the 22-40 gearing or head gasket mod. Will the clutch kit still be a huge improvement? Didn't want to do the head gasket due to crappy gas at some stations. I didn't do the gearing due to still having the stock track. Any advice? Also I assume the engagement ships go on the spring but what side? And lastly can anyone explain twist on the helix? Thanks in advance.
