Head Hoggers 124″ setup 14 Dec, 2016 in Head Hoggers tagged harley engine kits / harley head porting / harley machine shop / harley machining / harley service / Head Hoggers by headhoggers This is a engine we are setting up for a customer. Setup is a 124″, our custom CP 124″ pistons, HH stage 3 SE110 heads, HH ported HPI 58mm TB, Woods TW9F6 cams and setup for 11.8:1 compression. Should be nice setup!
