Can the seals be replaced without removing the head and if so how i get smoke after an overnight set on thes cool mornings i think this is the problem because i can smell the oil burning it quits after about a minute

Please revise the last part of your post they smoke because of the stem seals leaking they are made of rubber so they don't last forever mine are in need of changing as for replacing them you can get a device that compresses the valves with an air compressor or there is also the rope method where you feed a rope into the cylinder and rotate it up to the top

This is not a simple job.

I have done it a couple times on different trucks.

You will need about six hours if you have never done one before.

You will have to adjust your valves afterwards if you have mechanical adjusters.

If you don't know what I am talking about, you are not qulified to do this work.

Tweaker is right! This is not a task for a normal do-it-yourselfer. This job is very critical and time consuming (s/p?). If not carefull you can destroy the upper valve train and in some cases even the engine.

if it needs seal and you can change out a head gasket just take the head to the machine shope have it resurfaced and thave the seals and valve guides done as well save future headaches
