Default Breather Question

I have an 85 FXR which is a crank case breather and am putting a set of S&S heads on it that are head breathers. My question, should I run the head breather with the crank case breather or plug the heads. It is a stroker with mild compression...what say you.

My 94 Ultra had a 113" S&S motor in it when I got it. The shop had both ways running together into a "T" and exiting below the frame by the tranny. My 96" in it currently only uses the head breather exiting the same place.

Your OEM rocker covers assembly's are different than head breathers so plug them...
