Ford 289 Head Bolt Torque Specs and Sequence
Ford 289 Head Bolt Torque Specs and Sequence with application boundaries, staged tightening guidance, reuse cautions and official service-information lookup.
The 1966 Ford shop manual specifies three progressive cylinder-head passes for the 289: 50 lb-ft, 60 lb-ft, and a final 65–70 lb-ft, following the illustrated sequence.
The 1966 Ford shop manual specifies three progressive cylinder-head passes for the 289: 50 lb-ft, 60 lb-ft, and a final 65–70 lb-ft, following the illustrated sequence.
These stages apply to the documented 1966 production 289 with factory-style iron heads, bolts and gasket. Other model years, Hi-Po combinations, replacement aluminum heads and stud kits must use their matching Ford or component-maker instructions.

Ford 289 Head Bolt Torque Specs
| APPLICATION / ITEM | SPECIFICATION | NOTES |
|---|---|---|
| Pass 1 | 50 lb-ft (68 N·m) | 1966 Ford sequence |
| Pass 2 | 60 lb-ft (81 N·m) | Repeat complete pattern |
| Final pass | 65–70 lb-ft (88–95 N·m) | Production 1966 289 |
| Later 302/5.0L | Different procedure | Do not transfer bolt-group values |
| Aftermarket heads/studs | Component-maker procedure | Lubricant-specific |
Clean the block's bolt holes and confirm every bolt length before lowering the head over the dowels. Apply only the thread treatment prescribed for the exact gasket and hardware, then complete each pass across the entire head before increasing torque. Do not substitute later 5.0L long-bolt/short-bolt figures for this 1966 procedure.

Ford 289 Head Bolt Torque Specs and Sequence FAQs
What is the head bolt torque on a Ford 289?+
The 1966 Ford shop manual specifies three progressive passes: 50 lb-ft (68 N·m), 60 lb-ft (81 N·m), then a final 65–70 lb-ft (88–95 N·m), following the illustrated sequence.
Can I use 5.0L Windsor figures on a 289?+
No. Later 5.0L long-bolt and short-bolt figures must not be substituted for the 1966 procedure — that is a different bolt-group arrangement.
What should I check before lowering the head on?+
Clean the block's bolt holes and confirm every bolt length before the head goes over the dowels, then apply only the thread treatment prescribed for that exact gasket and hardware.
Should each bolt go straight to final torque?+
No. Complete each pass across the entire head before increasing torque, so the gasket is compressed evenly rather than being pulled down at one end first.
