Yes but I haven't had to adjust those yet. It seems like a pretty good transition... They have Holley secondary Jets and their own standalone metering rods and primary Jets. I just found out a trial-and-error that they do have the same step up Springs as the Edelbrock and I believe they have the same acceleratorpump as well and I think some other part that I can't remember. Post 1489 on the last page kind of has a rundown on the step up Springs of both.. the difference you can see is between the 6 and the seven spring.. one has one and one has the other but all are the same.. there's one major difference Edelbrock Springs are about $9 a set and the Demon Springs I got $27 a set remember , ×2..
