Hemi intake bolt torque specs

[AR67GTX]

I bought from Mancini. They were pretty much identical to the ones I removed which I suppose were original - but can’t be sure. I wouldn’t use all thread either as you end up with a coarse thread fastener instead of fine thread to torque. But with the minimal in-lb torque spec on these manifold bolts I don’t think they will be over stressed.

Edit: I think my comment on fine threads was a little off as that would only apply to the 6 studs the factory used. Unless I’m completely off and thinking of my rocker covers or oil pan studs.

Using SS all thread with anti seize....holds torque well and no issues to this point.....

My current Hemi is mostly studed throughout. Intake, carbs, rocker covers, heads, rockers and stands, water pump housing, front plate, mains, cross main side studs, oil pan etc.
