Custom SE110 heads25 May, 2017 in Head Hoggers tagged harley engine kits / harley head porting / Harley Performance / harley service / Head Hoggers / motorcyle dyno tuning by headhoggers Here’s a set of custom SE 110 heads we just finished up. These are going on one of our 117″ setups. This should be a pretty nasty kit on this one. Will get dyno sheet from customer when done.
