Head stud location help.

[jjk]

I’m close to bolting my head down this weekend and was prepping bolts when I noticed a couple of different length shoulders and studs in the pack. I did some hunting and couldn’t really find a location chart and I didn’t take note when I removed the old studs on length etc.

Would anyone be able to point me in the right direction so I don’t fumble the stud location ?

The top bolt in the photo is a quantity of ten in the pack the two lower bolts are the ones in question obviously the longer bolts are water neck so they aren’t photographed.

the same two sizes are for water neck to head and the longer one is number 8 to hold the cable to distributor if using the bracket..

You should have only one of the longer bolts in your picture for the ignition cable like Gary mentioned. You should have eleven 3 1/2" studs
one 3 3/4" and the two long for the water outlet.

So one of the studs is incorrect

I also should mention this is the high compression stud kit.

No, the 3-3/4" stud goes in the #8 position (middle row, second one up from the rear) to hold the clamp for the ignition cable.

But he has two of the 3 3/4" studs instead of only one.

I recommend that you incorporate this tip:

Who did you buy the studs from?

I only remember 2 sizes from my high compression upgrade.

The one with the longer coarse threads is not a head stud. Either made wrong or wrong application. At second thought, it’s the correct length, just has too many coarse threads. I suppose you could use it. Just set it at the proper height and you’ll have threads in your head. Don’t think that would hurt anything.
