	I buy alot of these
Use these springs on many engine builds. Use to buy the same basic spring from CompCams. Almost sure its the same spring. Cant beat these for the price.

	Broken Intake Valve Spring : 3700 miles, .488 lift
Broke one of these HTC2424s on the #4 intake valve on my 355 SBC. Street driven only, 10.25:1 compression ratio in my Model A Ford hot rod. Only have 3,700 miles on the motor. Hoping this was a fluke and not an indication of future failures.
