LS7 Valve Size Question
LS7 Cylinder Head: I need to know the Overall Length and the tip length of the Intake and Exhaust Valves that come from the factory.
Does anyone have this information?
Thanks in advance!

Manley lists the following in their catalog.
Intake: 5.200" LOA, 0.300" tip
Exhaust: 5.230" LOA, 0.290" tip
No guarantees that's the exact same as stock. For one thing, the stockers use a lash cap on the intake.

Gannet - Thank You! I checked Del West, Ferrea, Xceldyne, and Rev, and didn't think to check the old standby Manley.
THANKS AGAIN!

I measure 5.125". That does not include the lash cap.
The official GM spec is 5.123" +/- .005"

Those are probably steel valves with no lash cap which explains why they are .075 longer (to make up for the lack of a lash cap).

Thanks for the specs, I appreciate it! Is that for Only the Ti Intake Valve? I would assume that the exhaust valve would be a bit longer (without the use of the lash cap).
Do you have a measurement of the exhaust valve?
Thanks again!

The book shows the exhaust valve is the same.
