Important:
Wear eye protection when
changing valve springs!
When changing valve springs while the heads are still
in the engine you MUST ensure the valves do not
drop into the cylinder. This can be done a few ways.
1) Use compressed air to fill the cylinder and
hold up the valve.
2) Ensure the piston is at TDC so the valve can
not fall into the cylinder

Thank you for choosing COMP Cams

products; we are proud to be your manufacturer of choice.
Please read this instruction sheet carefully before beginning installation, and also take a moment to
review the included limited warranty information.
Valve Spring Removal
1) Remove valve covers.
2) Remove rocker arms and leave the rocker stand on the cylinder head. LS7s have the rocker
stands cast into the cylinder head already.
3) Pre-lube the threads of the bolt with the ball end and the pocket of the H-beam where the ball
end of the bolt sits with the supplied cam lube (COMP# 103) to reduce friction.
4) Install the Comp Cams Valve Spring Removal Tool on the cylinder that you wish to remove the
valve springs from. LS7 head applications (with cast-in rocker stands) will use the shorter pair
of included M8 bolts, and LS1-6 heads (with removable rocker stands) will use the longer pair
of included M8 bolts. Mount the tool to the cylinder heads using the rocker stands. Tighten the
included metric bolts to 15-20 lb/ft to hold the tool firmly in place.
Note: The included bolts cover most applications but always check that 1/2” of threads
are fully engaged before using this tool.
5) Make sure that the valves can not fall into the cylinder, see important note above.
