I’ve never had clearance issues with my set up. Maybe I have a Tii booster. (Haha. Wishful thinking) I ran a 45DCOE with smaller chokes. I don’t remember my jetting, but I’ll look around my garage. I have them written down somewhere. Also, I ran it on a stock motor for 5 years with flat tops. No problems. Fun set up. I just recently swapped my head to a 121ti head with a Schrick 292. A tad bit more fun now. Sent from my iPhone using Tapatalk
