Hi All, Had another Cam install question.....Putting a cam with .529 lift in my zz4.(Stock l-98 heads) Will the stock stamped rockers handle that lift or should I upgrade to rollers??

Thanks
Chris

i would definately be using screw in rocker studs.
as for the rocker arms, you'd probably have to grind out the slot a bit for clearance, and they should probably hold up as they are very strong. if you use them, be sure to get new grooved rocker balls and lube everything like it was a cam.
i ended up using comp's roller tip stamped ones because of the more accurate ratio and to ease up friction on the valve tips. got em off ebay for under a hundred bucks!
