Why such low compression? I'd bump it up to at least 11.5:1 maybe closer to 12.1:1 if you can get pure 93 octane and have a good tuner available.
For the cam I'd get a custom grind done. Pat G has always turned out good results. I used Advanced Induction for my old LS1 custom grind and it was great.

255-271-115,LSL lobes , but more comp, 12.0:1 with 30-35 thou quench.., The fast hurts the top end, spreading the lobe centres helps it hold on but you drop cylinder pressure doing so. So increase static compression to compensate.

Your compression is pretty low, I would bump it up to 11.5-11.75:1 if you can.
Here is my recommendation...
247/263 .660/.660 @ 1.8 rr 112 LSA 110 ICL or (.624/.624 @ 1.7 rr)
It will have roughly a dynamic compression of 8.35 if you go with a 11.75 static compression, which will keep it 93 pump gas friendly.
Brian Tooley ran a 251/266 .660/.660 @ 1.8 rr 115 LSA in his 454 LS7 build which had a FAST 102 mm and TFS 245cc heads.
