IMPORTANT NOTES:
- You must run a dual spring with these valves due to the added mass in the valvetrain. With single springs and larger than OEM valves, valve float will occur which can cause damage to retainers locks, valves, head, piston, turbo, and wallet.
- When using the Warhead valves use a 1.550" diameter spring and GM retainers.
- When machining valve seat on OEM head to fit these larger valves, make sure you set valve face at .055" from cylinder head surface.
