Same length as the bolts in the 61's intake but 4mm.
I dont know the exact length but you should be be able to figure it out with the 61's bolt in your hand.

I think the 61 block bolts to the cylinder and then 2 different bolts go through the carburetor and into the block. On a 272 the bolts go all the way from the elbow to the cylinder
You will need the sleeves as well.
If you are doing the 61 to 268/272 mod you need the 272 intake, complete, as shown. You cannot just use the 61 parts.
