OK. I started this thread, and I'd like to bring it full circle now. I have completed the cam swap (Brenspeed Detroit Rockers). I DID NOT use the spring compressor, and I DID exercise great caution while drawing down on the new cams. No problems were encountered. I tried to perform the driver side using a simple hose wedged into the chains, and that proved to be somewhat difficult. I used a home-made plastic wedge on the driver side, and the install went a bit smoother. The secret is to get enough slack in the chain, without slacking the lower end, to ease installation of the phaser.
I had an issue spending $90 on a "chunk of plastic on a stick", so I made my own for free. If you are skilled enough to change a cam, you are qualified to make a cam wedge and save $90.
I saved money by not using a spring compressor, but I was extremely careful. I must admit, I do see how this can go wrong, and there are lots of potential pitfalls. If you simply take your time and watch every move, you'll be fine without the spring compressor.
My only issue was with the driver side cam phaser. While fidgeting with the sprocket on assembly, the phaser slid off. I discovered that the roll pins that locate the phaser were damaged. I replaced them and finished the job. The damaged roll pins were most likely a result of me tugging on the sprocket (not enough chain slack). Slack is the key....
Bottom line. Change those cams without spending money on special tools. The cams are expensive enough on their own. No need to spend more money on tools you won't use often...
Just my opinion. I want to thank everyone who offered help and ideas. I appreciate it.
