Most people run the LS7 head on a 4.125 bore but the new 327 COPO motors are running LS7 stock valve heads on a 4.065 bore so it obviously can be done. As said above, unless it's been sleeved, I'd be more concerned about running your block with a 4.100 bore than valve shrouding.
Also, what cc piston are you running? Without knowing head gasket and deck height, you'll need roughly a 20cc dish to even get you close to 11:1 with these heads.

The blocks been bored after sonic testing so its fine. I'm sure I can run them just want best bang for my buck. I think the wiseco pistons are 11cc if I remember correctly

Just looking on GM's COPO website there are a couple of the COPO configurations running a 4.065" bore and LS7 head with 2.20 / 1.61 valves. All are shorter stroke setups though.
