This 65g lightweight beehive spring is Katech's default for all engine packages. Optron valvetrain dynamics testing revealed this spring was the best choice to keep lightweight valves such as LS6 and LS7 in control.
Katech recommends coil bind clearance of .050. This allows you to use the PSI-1511 valve spring at lift heights up to .650
