Test Fit Head Gasket

What happens here

After the engine block's threads are prepared, the new head gasket is placed onto the engine block for a 'test fit.' This allows the technician to ensure the gasket is oriented correctly and aligns perfectly with all the cylinder openings and dowel pins on the block. A proper test fit prevents misalignment issues when the heavy cylinder head is eventually lowered into place.

Goal: Verify correct placement and fit of the head gasket on the engine block.
