Each engine block is bored and torque plate Extreme platou honed with ARP 625+ Head studs to our specific piston to wall clearances, The deck surface of the engine block is then milled to a very smooth RA (Roughness Average) Which provides an excellent seal for MLS (Multi-Layer Steel) head gaskets. All of our blocks include ARP 2000 Grade main studs, and are line honed to ensure the main bearing tunnels are straight. Balance shaft bearings are then flipped to block off the oil feed supply, and our balance shaft delete kit is installed on your engine along with a brand new Mitsubishi OEM oil pump (Optional) Wrist pin clearance is set to our desired spec, and the connecting rod big ends are checked/adjusted for roundness. The rotating assembly is also fully balanced to within +/- 0.5 grams.
