Step 1: Disassembly and Inspection
The journey begins with disassembling the engine into its component parts. This includes removing the intake manifold, cylinder heads, pistons, and crankshaft. As you disassemble, meticulously inspect each part for wear, damage, or cracks. Note down any issues that require attention and determine if any components need to be replaced or reconditioned.

Step 2: Cylinder Block Preparation
The engine block forms the foundation of the engine. It houses the cylinders, crankshaft, and other critical components. Prepare the block by honing the cylinders, fitting new piston rings, and installing new main bearings and cam bearings. Ensure the block's surfaces are clean and free of any imperfections.

Step 3: Crankshaft and Connecting Rods
The crankshaft and connecting rods work together to convert the reciprocating motion of the pistons into rotational motion. Inspect the crankshaft for any bending or damage and have it reground if necessary. Replace worn connecting rod bearings and ensure they are properly sized and clearance checked.

Step 4: Cylinder Heads
The cylinder heads are responsible for housing the valves and combustion chambers. Inspect them for cracks, warpage, or damaged valve seats. Have the heads resurfaced and replace worn valves, valve springs, and seals. Ensure the heads are properly torqued and timed to the block.
