440 power gains/ aluminum head advantages?

Remember IF you find rhe timing is off, you can play the game of using offset bushings or keys or whatever or even in combo with a tooth off to get the cam where it belongs. I've done that before as it really doesn't matter "how you got there" so long as the cam ends up where it's supposed to be.
took my intake off and inspected cam lobes and lifters from what i can see before taking it apart. it looks good even wear patterns on every lobe and they're offset good and all lifters rotate and they all are the same length from the eye. there's no rings on the cam lobes ha. so far so good. i got my cam degree kit this night, so i will start on it tomorrow and see how it plays out. also got the timing kit in the mail too.
