I run the TFS springs on my 93 with p heads and TFS stage 1 cam. I have had no problems and they are pretty easy to install. The big thing is to check the installed height and use the included shims to get to the correct 1.8" installed spring height and that there are separate spring retainers for the intake and exhaust valves to compensate for the factory rotators on the exhaust valves.
The kit comes with seals, springs, retainers, locks, shims and spring height checking tool. I did mine myself. Just have a good spring compressor to make your life easier.
