You don't need to bring each cylinder up. The pressure from the hose is plenty
to keep up. Bring #1 up so it so it's on the firing position before you do
anything and leave the engine rest there. Makes it much easier to readjust the
valves once you're done. It's a pretty straightforward job. Should take about
an hour. When you remove the rocker arms and have the tool in place, compress
the spring, pull the keepers off, then release the spring. Pull it off, pull
old seal off, then slide the new seal on, reverse the procedure, and your done.
Just make sure you adjust the valves properly....there is a specific sequence.

Subject: [Chevelle-list] Valve Seal Replacement ?
I am going to attempt to replace the valve seals on my 350 this weekend.
I've never messed with heads at all, but am thinking it can't be too difficult.
I have an air hose adapter to keep the valves in place and bought a valve
spring compressing tool at Pate last weekend.
I'll bring each cylinder to TDC, apply air, and use the tool to compress
the spring and remove retainer & keepers.
I am assuming that the seals just slide over the valves.
Is there anything more to it than that? Any Gotchas? Do I lubricate
the seals before sliding over the valve stem? Are the keepers easy to align
when I reassemble? I googled Valve seal replacement & didn't find much to
help. Anyone know of a web site with pictures?
Thanx
