Apparently head bolts on the M8 are subject to failure.... take a look
Anybody have this issue?

Not me, but my engine is stock internally.
I do recall HD having problems with M8s blowing head gaskets & its my understanding they went to a different head gasket.
2017 Harley Davidson Freewheeler (107 cu.in. vivid black).
Me either... that is why I am asking if anyone else is seeing this. Moonshine HD is a dealer that builds a lot of engines. I like their videos and get a lot from them. Early in the video the mechanic refers to head bolts breaking on engine build upgrades (Stage 3&4 type stuff). I have effectively done a Stage 3.5 to mine (Stopped short of going with bigger bore cylinders) so it caught my attention and made me wonder in anyone else had seen or heard of this issues.
There is a fix (S&S Head Bolts), but I don't want to tear into the engine again.... the paint is almost finished....
Good info Jeff
I have heard of some head gasket leaks, but not broken bolts YET

I would assume so, Woods M8-22X Cam = Higher torque and response time to achieve it... generally leads to higher compression. The larger throttle body will allow more fuel as well. But the good news is there is essentially a tuned straight pipe in the exhaust as I have cobra headers and SVT Boneshaker slip ons
