yes they are hypereutectic pistons. i recieved the car like this so im not sure what machine shop did it. also i just put a different intake on it and it still smokes so im guessing it isnt from the intake. it also smokes alot out of the oil breather when idling if that changes anything. i havent done the compression check on it yet thats will get done this weekend. i appreciate all the help and will continue to update all info i can. thanks
