Close up of 426 street hemi intake bolts/fasteners

[hemi68charger]

Hello all...
I'm getting ready to bolt/torque down my intake manifold on my '68 426 Hemi. The intake manifold bolts have different lengths... I wanna make sure I get the right fasteners in the proper intake holes. Anyone with close pics of the intake? I know some positions have the threaded end for the nut and some have the bolt head. All my brackets are OEM...

Thanks..
Troy

I hit the motherload of sorts...

I see pics here of both the allen and hex heads.. Does anyone sell the proper allen head style?

From what I'm hearing, it turns out the transition from allen to hex was done around the beginning of the year 1968.. So, with mine being a Feb. production date, I'll stay with the hex head bolts I already have..
