AA is not the guy in Georgia is it ?
AA is probably referring to AA Performance Products (Used to be AA Piston)
https://aapistons.com/. They are out of California.
The other AA is Auto Atlanta based out of Atlanta, GA. It can be confusing sometimes. Haha
I installed an AA Performance 2.0L head back in August after the exhaust studs on cylinder one completely fell out. I had the local shop take a look at the AA Performance head before I installed it. They said it looked great. Nice clean casting and the valve work was fine. I drive the car hard and haven't had any issues with it. In my mind a no brainer buy at less than $400 a head. I spent $1850 to have a pair of original heads redone only to have the exhaust studs fall right out. (I didn't over torque) the heads had broken studs from a previous owner. They time certed new studs in that didn't hold up.
