03 5.4

ok guys I think I will apriciate this one!! I have had this truck for a long time and it been in the family from the lot! It is my wife’s daily driver and it has 310000 miles on the original motor!!! Well I am starting to notice a big drop in hp plus it’s starting to take in some water somewhere. And it’s time to replace head gaskets. So any suggestion on who to purchase the kit from and should I do more while it torn apart?

I can't think of anything else to do while in there. Other than make sure to have the heads pressure tested and checked to trueness.

Ok good deal! Should I go ahead and replace all the timing chains and guides? Maybe go ahead and replace valves and lifters?
