need advice for top end rebuild

[NAREJEPP]

my 5.3 has been making some wicked valvetrain noise for quite a while now. i also notice that over the past year or so, the truck just doesn't seem to have the power that it used to have.
i was thinking about pulling the heads and getting them cleaned up, then go back together with all new parts (lifters, springs, etc.)

am i wrong in thinking that this will make a difference? with 200k on the engine, i think that it is just getting worn out. i use it to tow and do grunt work like that quite often.

anybody?

For the time and money you are about to spend, just buy another low mileage 5.3 block. Literally just swap your stuff over to it, and then run that. Those things are a dime a dozen

I vote total build up..... Cam, heads, and all the needed stuff

x3 on newer motor...why put heads, cam etc on a 200k mile motor? thats just gonna put more stress on the parts that are already worn out
