Why choose matched valve springs for performance cams?
Spring pressure must match the cam profile and rpm limit. Too little causes valve float; too much causes wear.
Do I need adjustable cam gears?
They allow fine-tuning of cam timing, especially useful after head machining or when running non-standard cams.
What engines is the LS7 lifter kit compatible with?
The LS7 lifter kit is designed for non-AFM GM LS engines, including LS1, LS2, LS3, LS6, and L98. It can also be used on AFM/DOD engines when performing a proper AFM delete, but it is not suitable for use with active AFM systems.
What should I do before installing the lifters?
Before installation, pre-soak the new lifters in clean engine oil to ensure proper lubrication. Additionally, use new guide (tray) bolts and follow GM's torque specifications for installation.
Do I need to check pushrod length after installation?
Yes, it is essential to verify the pushrod length and lifter preload after any changes to the camshaft or cylinder heads to ensure proper valvetrain operation.
Is professional installation recommended for the LS7 lifter kit?
Professional installation and calibration/tuning are recommended, especially if you are making significant changes to the engine setup, such as a camshaft upgrade or AFM delete.
What maintenance should I perform after installing the lifters?
After installation, prime the oil system and confirm oil pressure on the first start. It's also advisable to change the oil and filter for the run-in period to ensure optimal performance and longevity.
