Its sleeved! Open deck sleeves I installed them. The pistons are 84.5mm.
And heads do not determine if the motor has high or low compression. Pistons do. The head being milled only changes the compression by a few points.
We used the ls because it was a motor that had no home, with a cracked sleeve between 2 and 3. No theory behind it, was just avalible
