Compression Release ??

I have been reading several post, and talking to HD Dealer ...Still confused !!
I have a 2011 RG when purchased new had 103 kit , cams , tuner , and breather installed. It has always had issues when starting hot, Kicking back against starter. I have extended warranty and just took it in to HD and they told me they could set the compression reliefs ?? Do I have them ?? I still have the stock 96 heads.

What do I need to do to correct the problem ?

Thanks !!
