That may work if you already have them adjusted, but if you do it that way
initially after having the rocker arms off, you might damaged the lifters or
the camshaft. If the rockers are too tight, you risk wiping out cam lobes.

I like to adjust the valves with the motor warm and running. Back each
one off, one at a time, then tighten 1/4 turn past when they stop clattering.
An old valve cover with the top cut off comes in handy. They used to sell
clips that attached to the rockers and plugged the push rods to keep the mess
down. You can do each side in about a minute that way.

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
