If you have the heads off already, it's a cheap swap. There are better cams out there for performance, but that one didn't seem to really bother my Gen1 PCM as far as learning goes. With only OBD1, you'll be guaranteed a tail pipe sniff for emissions if there are emissions in your area. I've not found my PCM to be forgiving on emissions with the aggressive CAM. If you are not taking the heads off already, it's not worth the $ for the swap on a CAM at all. The gaskets alone will cost more than any CAM out there.
The only gasket you need is the timing chain cover and the crank oil seal. You can install the cam without removing the heads.
How do you get the CAM in with the lifters in place?

20 Magnets, Tony Armour, multiple dealerships and the viper wizard all use this approach.
Very interesting, especially on a Gen1 with the gaskets so expensive.
Any tricks to replacing a lifter with the heads on by chance?
Probably not going to help you now but perhaps later? VSP sells custom head gaskets that allows the lifters to be removed with the heads in place. I purchased these from Dan when i did my heads/cam last year. After everything was put back together, I had to replace a lifter and this gasket allowed me to access the lifter with a flexible extension. The gaskets paid for themselves.
