I have the 100hp flathead finished except for the intake. It is painted and installed, but I cannot find torque specs for it in my manuals, or online. I know that Ford had specs and an order for torqueing it, but I don't nkow what they are. Can anybody tell me what they are. Thanks in advance.

What we did on ours was 45-50 foot pounds and started in the middle of the intake and working outward in a criss/cross pattern. And we have had no trouble at all. Just start like at 30 or 35 foot pounds and work your way up to 45 or 50 foot pounds that way you torque them all even and you won't have any leaks. Good-Luck!!

 

The manuals say 23-28 ft/lbs.

 

I asked my dad today if I said that right and he said yes, but don't torque the bolts to 45-50 ft/lds. He said we torqued ours to 30 ft/lds. So do that instead of 45-50 or you can do what "mtflat" said to do. He's given me good advice more than once. I would take his advice over my own anyway. I'm still learning about the flatheads anyway.
