Send the cam back, order a XE274H from Comp. Set your motor up for no more than 10:1 CR. Zero deck the block, use a felpro 0.039" head gasket. Polish your combustion chamber smooth to eliminate hot spots. I don't know what springs you have but for the price it would take to machine the heads and put bigger springs you can get with comp and choose a bee-hive setup that is much better than standard style springs. The intake you got will work fine. Top it off with a Holley Street Avenger 770 CFM carb and some HEI ignition with msd module and coil and you have a stout street engine. You do need to try to get some better heads. Get some off ebay cheap. How much you looking to spend?
I'll be lucky if my wife lets me spend $500 on heads! This is the article I'm talking about, under articles at top and then look down the list for the "540 hp 195 cc heads" title:

They say that's a pump gas 540 hp motor. That's why I was very interested in it.
