2006 gto dyno day Spring time came, and was low on coolant, checked for leaks and none found. Took the heads off and found Both head gaskets were leaking. While I had it apart, replaced lifters. Ported the heads out by hand and had them milled a few thousandths. Last year ported the intake and throttle body. Went on dyno friday, dyno jet and made 375whp and 404 ft lbs. I was pretty impressed.
