I didn't use the tools. Removing the roller followers by using the spring compressor is completely un-necessary. Just "inch" the cams slowly off and on and you'll be fine. It's also faster and IMO safer that way (b/c otherwise you risk knocking keepers off and dropping a valve and it doesn't take much of a bump to do that!). I also improvised on the timing chain wedge. It doesn't matter that much what you use or how you do it, just keep the tension on the chain so it does not slip off the lower sprocket.
