Remove
 the following, valve covers, rocker arms, wire retainer,push
rodss,push-rodd tubes,push-rodd rock guards.
Clean the bores in the block (Berryman B12 works good). Clean the
push-rod tubes inside and out.
Install the new push-rod tube seals on the tubes (green = Viton) (reddish
brown = silicone) (black = neoprene)
Sealer isn't required but it doesn't hurt.
Lubricate the O rings very good, insert them thorough the head just
touching the port in the engine block. Use a small screwdriver to massage
the upper area of the Outer O ring so it will slip into the head. I use a
15mm socket on an extension to give me some pressure towards the block
when pushing the seals in.
Adjust your valves after you get done with the seal job. Use new valve
cover gaskets. If the wire retainers are missing ---- get a pair.
First time around never having done the job and being careful, this job
should take a casual 2 hours.
