Valve keepers for sure! I lost about 5 of mine doing my valve spring swap. It held me up a lot for nobody local had them in stock. Use the dowles for the lifters, it's the easiest way. Pen magnet for sure when removing the keepers. Gear ratchets are a must. I removed my condenser and radiator to allow easy acess to the cam and oil pump, etc.
Trust me, you think you have it all, and all the sudden $500 adds to it. I would know.

Amazingly, I didn't lose one lock during the install. Of course, the only reason they didn't is because I had extras on hand, so they knew better than to go flying.
