Depends on how many miles are on the springs now. They are not too hard to change on the car, just a pain in the ass. You will need a tool for this, I used the Krbian’s tool and it worked OK. One work of caution, if it has the original timing chain and sprocket set you need to replace them at the same time when you do the valve springs. The reason is that the cam sprocket is nylon to dampen false knock and after 20+ years they become brittle and if you add new springs it will be too much for the old sprocket. I found out the hard way, I installed new valve springs and in less than 100 miles I spun a rod bearing and lost a new turbo that I had installed when I did the valve springs. The cam sprocket had become chewed up and all that nylon went to the oil pan and onto the pickup. It had even blocked off the bypass on the pickup. If you know the history of you car and that it has had a new timing set installed you are good to go, but if not don’t take a chance.


Good luck,
Jim

If you're going to run more boost than stock (which you are ;) ), and you plan on turning the car past 4400rpm (which you do :cool: ), you're gonna need to replace the valvesprings with something better than the same ones GM had been using since 1979.

I made my own tool to do the job, based off the Kirban tool, but much better.

It's more than just body guys. I signed off on the insurance estimate on the motorcycle like 6-weeks ago, and was told it would only take 2-weeks... :rolleyes:
