I have "performance" pistons and the head might be a little lower than stock. Thanks for the video.
They are forged, and advertised as "racing grade". They came with the car from the previous owner. Not sure of the brand but as far as I know most performance pistons are designed to improve compression.Are they stock replacement pistons or are they forged JE, wiseco etc
