generally like most said the cam is the important thing. one thing i try to do is match the powerband of the cam to the power band of the intake. but one thing to consider is the tighter the lsa/lca, the more lope you are going to get. the wider the lsa/lca the smoother the idle. but the xe256 should work great for you. me i am going to be running a lunati 503a1lun in my tpi. the powerband is very similar to what the stock tpi powerband is and i am having my heads cut to fit the .492 lift that the cam has. but what ever you choose make sure that your heads can take it. otherwise you are going to have to have either offset valve locks/have the guides cut to clear the lift. and make sure to use the recommended spring/retainer that comp recommends
