Just wondering how much of an increase in compression I would end up with just changing HG? Bike is a 2014 stock 103" and looking for the simplest (cheapest) way to get to 10:1 cr. 

thanks.

Should gain you around an extra 0.25, and take you to where you want to be.

i would shave the head 20+ thou if ya going to the trouble of taking the head off her just for the head gasket only & piss off da stock EPA  cam  & take more off da head

dont be shy with her todays fuel likes a bit of comp to burn it up ,  that way you can have more fun & burn up da road too

yep 57h cams with .030" HG would be spot on

I will add it would be a shame not to have the heads cleaned up a little at the same time, still keeping the stock valves.

short back & sides
