After almost a full day digging around online, Ive learned that I can simply drill and tap 3 holes on the 22R head and make it work . Unless there is something I've missed. I grabbed this injection setup for $50. It came with everything but the fuel pump and the air filter box. I've looked into propane and just still a bit heistant on it. I could see me running out of barbegue juice in the middle of a trip and be screwed. Also, I work on cars all day everyday and have seen propane burn valves on alot of street vehicles. I got lots of buddies that have it though and are happy with it. I am sure I'll get there someday
