1969 Camaro 350 Small Block Head Bolt Torque Specs

The numbers

For the stock 1969 Camaro 350 SBC with iron heads and factory bolts:

• Long head bolts: 65 ft-lb final
• Short head bolts (around the rocker shafts and ends of the head): 60 ft-lb final
• Sequence: start at the center, work outward, in three passes
• Pass values: 35 ft-lb → 50 ft-lb → final (60/65 depending on bolt position)

Lubricate the threads with engine oil before installing. Do not use anti-seize on factory bolts — it changes the friction coefficient enough to over-torque the clamp load.

The pattern

The 1969 Camaro 350 head has 17 bolts per head. The factory pattern is the same as every small-block Chevy of that era — center bolts first, then alternating outward in a spiral. If you have the chassis service manual, the diagram is in Section 6. If you don't, the canonical pattern is:

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 (center to outer corners)

Most aftermarket and OEM-replacement bolt sets ship with a printed copy of this pattern. If yours didn't, search "SBC head bolt sequence" — any decent reference will show the same diagram.

When to deviate

These are factory-stock '69 Camaro 350 SBC values. Use the head manufacturer's spec instead if you're running:

• Vortec heads — typically 65 ft-lb across the board (no long/short distinction on later Vortec patterns)
• AFR aluminum heads — usually 70 ft-lb with the manufacturer's hardware
• Dart aluminum heads — refer to the Dart instructions; they often spec ARP studs and 75-80 ft-lb
• ARP studs (any head) — follow the ARP instructions, which usually spec a different lubricant (their molybdenum grease) and a different final torque, often 65-70 ft-lb depending on the head
• Aluminum heads on iron block (any combo) — head gasket selection and bolt torque change; check the gasket manufacturer's spec

Big-block (BBC 396/427/454) cars use completely different specs. Don't apply these values to a 396 or 427 build — head bolt torque on BBC iron heads is 80 ft-lb final on the long bolts.

Common mistakes

1. Skipping the three-pass sequence. Going straight to 65 ft-lb in one pass distorts the head and often damages the head gasket — even if the gasket holds short-term, you'll see localized warping in the head and combustion seal failure within a few thousand miles.
2. Using anti-seize. It dramatically reduces friction and the same indicated torque produces 20-30% more clamp load — over-stretching the bolt or pulling threads in the block. Engine oil only on factory bolts.
3. Reusing torque-to-yield bolts. Most factory '69 Camaro 350 head bolts are NOT torque-to-yield (TTY); they can be reused if undamaged. But inspect each bolt for stretch, thread damage, and corrosion. If any bolt fails inspection, replace the full set — never mix new and used bolts in the same head.
4. Forgetting to retorque after the engine has run and cooled. Some builds — especially with composite head gaskets or aluminum heads — benefit from a retorque after 100-500 miles. Check the head gasket manufacturer's instructions.

Tools you need

• 3/8" or 1/2" drive torque wrench (capable of 75 ft-lb minimum, calibrated)
• Socket that fits the bolt head (12-point typically, 1/2" or 9/16" depending on the bolt)
• Engine oil (the same oil you'll run is fine — typically 10W-30 conventional for a stock '69 Camaro 350)
• Clean shop rag

If you're not sure

Triple-check the spec against your factory service manual or the manufacturer's hardware instructions before applying it. Head bolt torque is one of the failure modes that destroys engines silently — the gasket leaks coolant into the cylinder, the cylinder hydrolocks, you bend a rod. There is no "I'll just guess" version of this spec.

If you have GarageLog with a paid plan, the chat assistant has the factory reference data pre-loaded for first-gen Camaros and will surface the same values with the same caveats. Useful as a sanity check, not a substitute for the FSM.
