Replacing the head gasket on my little G. There are 2 different lengths of head bolts. Can anyone tell me where the longer ones go? The parts book shows 6 long ones were used, but does not show their location on the head.

Many thanks!

Can you not stick a wire down the holes to see where the long ones go?

Looking at the parts book I have it looks like the longer ones go in between the cylinders and the shorter ones around the perimeter.
