Shoot, in that case I'd put in some SE211s, but that's because I like the sound of a nasty idle.
I probably wouldn't put 255s in a softail, but there's lots of guys that do. The stage II kits from the MOCO have 255 cams, no matter what the platform.
******* my apologies for the thread hijack ***********
how in the world did 255s wind up in a woods 6/555 thread. LOL!
