Ring Advisory
The lower readings on cylinders 3, 4, and 6 are consistent with rings stuck in their grooves from sitting — very common on this family after storage. The block, pistons, and crankshaft are all in good shape.
▶ Option A — Easy: Apply penetrating oil (Break-Free or equivalent), let it soak, then run the engine. Rings typically free up with heat and compression.
▶ Option B — Thorough: Pull the pistons and clean the ring grooves directly before install.
This is a good block. The rings are the only item that needs attention.
