I have a zz4 cam i want to install into my l98 with iron heads. I'm wondering what valve springs and what else I am going to need. I don't want to do any machining to the heads and I don't want to spend too much. Will the LT4 hotcam springs fit? I was thinking about these http://paceperformance.com/i-6255251...-diameter.html

To do it without cutting the guide bosses, you definitely need offset locks, +0.050", or beehive springs to clear that 0.510" exhaust lift. Maybe both?
You also need to check if your rocker slots are long enough.

Thanks SiCkRs and ronnjonn! Will I need to replace my rockers, or can I keep the stock rockers?

You will need to run screw in studs. I pulled several press in studs out with the ZZ4 cam.
