What all is involved in replacing 4.6 valve seal gaskets? It looks like timing chain and cam and all have to come off? I got the air hose for spark plug compression and valve compressor I took valve cover off but now looks like cam and timing chain have to be removed? Help???

I am by no means a Mod motor specialist. So hopefully a few that are will chime in. But every time I’ve ever had to change valve seals-the cylinder heads where sitting on my work bench

And here’s an older thread on this forum with some decent info

Valve guide seal replacement

What all is involved in replacing worn/leaking valve guide seals? Does the motor need to be pulled? My seals are leaking pretty bad and I'm trying to get an idea as to what I'm in for.
