If you haven't picked the cam then how do you know what valve spring pressure you're going to run? If you don't know the springs then how are you making the decision on lifters? Comp lifters will last a long time on some lobes. Crane lifters can handle a little more load, etc. A typical 500 inch Mopar is going to be all finished by 6500 with 270 heads so you don't need the super high end stuff in the valve train.
If you're plugging up the engine with a Trick Flow intake then it isn't going to be a high rpm monster anyway. Do yourself a favor and call Dwayne at Porter Racing Heads. He can work with you to spec a cam and he'll tell you the matching springs and lifters to go with it.
