I have them on my 632. No problems here. Although the motor seems to be down on power but that could be due to anything.

Have a set of 385's on a 598 bracket style build. 125+ plus runs a year, cam around .800 lift, single carb, stud rockers, and super vic. Has gone 181MPH at 2550 punds on a single .028 jet. There alright but there are better choices now if buying new. And they flow no where close to as advertised.
