My Corvette started exhibiting some of the signs (ticking sounds from the heads, blue smoke on startup, etc) knowing that I cant afford to replace a $15,000 engine if I dropped a valve, so I decided to take my Vette up to Vengeance Racing in Cumming, GA this past Friday for Vengeance Racing LS7 Cylinder Head Upgrade. they typically can hand you the Vette back in 24 hours, but I wouldnt be able to get back up there that quick due to work and other stuff. I will be picking the Vette back up on Wednesday the 18th
