All questions will be displayed after moderation. All answers will be displayed after moderation.

Do you have the manifold studs for the 226 engine?

Willys Jeep Parts Tech:
We can help with good used.

Do I need to put anything on the studs to help seal the coolant in when I put them into the block?

Willys Jeep Parts Tech:
I would put a thin layer if possible.

What is thread size that goes into the block? Are they all the same going into block, or are some fine and some coarse thread?

Willys Jeep Parts Tech:
They are different on either end. One side is course one side is fine thread.

The photo shows two stud lengths, can you tell me the different lengths of the two and where they mount?

Willys Jeep Parts Tech:
2" and 1-3/8" in length. If you check your manifold you'll find different thickness they have to go thru.

I only see 5 bolt holes on the exhaust manifold for my 56 cj 5. Why are there 8 studs?

Willys Tech:
This fits a number of vehicles. We give extra. I believe there are more than 5 on yours.

Do you have the nuts for these studs?

Willys Tech:
Yes, the number is B0109. Thanks
