Called s&s and they said this could be done with no problems. I had ran a hose from front breather bolt to rear breather bolt and a hose from rear breather bolt to puke can but was still getting a little blow by from crankcase vent which also attatched to backing plate. So ran crankcase vent also to the same puke can with a filter on top and now blow by from any of the three can only go in can. Just thought i would enlighten on what i did and that s&s said this would work fine. I have the older 107 breather system with breather bolts for venting the heads.
