Fabe,
The valves are standard 7mm
The springs are PAC, recomended by Catcams. I can't remember the length, and spring rate. But I told catcams that i was planing on around 8500 RPM. They thought these springs was the way to go. But cant make any guarantees. The thing to do is to slowly increase the rpm's to your target. When they begin to float it will be seen on your dyno results. And will also most likely be heard by your ears too. And if they peak at 7500 RPM, it wont matter anyway.. :-)
...."Last spring i sold a complete set of S54 (E46 M3 Engine) Schrick race cams, with springs and DLC coated lifters to a customer. Even Schrick woulden't make any guarantees as to the RPM limit. But they proved good for 8500 RPM as expected."....
The retainers are steel, as are the lower spring pockets.
The adjusting shims (Shim under) are Schrick.
Extra adjusting shims are included
The lifters are Catcams solid lifters.
The setup are rather light (Please see my former posts in this thread)
The valves are freshly lapped
The valve seals are new also.
The valves are adjusted to spec.
I'm sure i forgot something, let me know...
