I have an 01 GT (Stage2 roush #4682) and I just started to get a pretty bad click/knock from what I assume is the valves and it started to miss (sputter) a bit as well. Not real sure which way to go to repair, replace the whole valve train or just bite the bullet and buy new heads, just looking for some advice. The real question I have is will 02 heads from a Lightning 5.4 (2V) fit on my 2V 4.6? I have a set sitting in my garage that are perfectly fine and would love to swap them out if possible. Any advice/suggestions would be welcomed. I would be happy to give a list of mods to the vehicle if needed, but as far as the engine (internals) is concerened, its pretty much stock.
Thanks guys and I look forward to hearing from you.
