These look great. I put them on my 88” S&S EVO. Had to run a 1/2” spacer on them since the thread depth of the head breather holes is shallower on the S&S than on the HD EVO heads. Still worked out great for me. I have over 1,000 miles with them so far. The oil weeping is minimal. I will run these agin if I build another EVO.
