Re: Comp XR286
I run the XR294HR. It came with the 986 springs and I would recomend you move up to them.
It's my understanding that the HR cores are not billet steel but are "harder" iron so you don't need to worry about the distributor gear. I ran mine one year with a stock distributor gear then changed to a melonized gear. When I pulled the distributor the old gear looked brand new. I changed anyway just for some piece of mind.
