Replacing Valve Seals tomorrow, tips?

[xtreme80]

I've never done this before, so any tips would be helpful.

We're keeping the heads on the truck. Gonna use compressed air in the chambers to keep the valves up.

Do I just pull the old seals out with a pick, and push the new ones in? Should I pre-lube them? I'm doing all 16 so I wanna make sure I do it right.

I guess next question would be about how to adjust valve lash once I get it all back together? My dad doesn't use any special tools to do it, but he's been a tech for 30 years. I don't know if my lack of experience should require me to use special tools.

Any other tips and tricks are more than welcome, so I can get this done right the first time and drive my truck home tomorrow.
