cylinder heads and camshaft

[MTChevy]

I am currently building up a 350 i got in trade. It has some goodies, but i want to go all out on this thing. The heads it has now are 333882 castings. 1.94 intakes yada yada. bone stock. it has these pistons in it. http://www.jegs.com/webapp/wcs/stores/servlet/product_10001_10002_57952_-1

its bored 30 over. I want to get some better heads on it. I was thinking going the bare route and came up with these 2.

I want to be able to get some high end HP out of this engine and figured heads would be the first place to start. Also it has this camshaft in it right now.

What should I do here?

With those pistons I would definatly get another cam. The cam you selected is only good up to 10 to 1 comp ratio. It is a low RPM cam. I would guess with 76 cc heads that engine will be around 10.5 to1
If you are planning on running pump gas i would go with some 76 cc heads to keep the compression ratio down.
