Thanks for the feedback!!!
I hope mine turn out so well.

Flat or angled squish bands?

That’s with 30 degree angled squish bands.

Also, a note for anyone installing the Impact 560s...check all of your clearances! I just had to slightly chamfer the #2 and #3 cam lobes with an angle die grinder so that they would clear my pinion race. My Jackhammer 570s did not require this. A little nerve wracking but easy to do with the right tool. I did a practice run on a bad Andrews Ironhead cam I had laying around. It’s worth keeping bad cams for times like these.

That's interesting. No good reason the 560's should hit and the 570's clear... but that does reinforce the need to check...

Anybody know who grinds Harleys' SE cams?

Ya, it surprised me.

It’s always been my understanding that Andrews grinds the SE cams. Someone correct me if I’m wrong tho.

Ive got 560 cams in my 2014. When I purchased I asked Hammer would I have to clearance for them. They said not needed for a late model and they were right. In my case.

Stole a page from you and did this. The Buell bracket put to much of an angle on the A/C for my liking. Thanks for the ideal.
