I’ve learned a lot on these heads since I did the set on my duster right now. 8 years ago when I did them I couldn’t get them calmed down with a bigger valve and had to rely on my intake to calm them down up top. I’ll have to look at my sheet again but the set I’m doing for my duster now are around 228-230 and nice and calm but boy I wouldn’t even do a set like this for a customer. The shortside is just so touchy but I’m sure you know that.
