   Dave,

   Let me know if you want this to be cross-posted over on http://www.OldWillysForum.com.

   Cheers!

   I’m not sure if they are still doing them, but, last year, I bought a set of headers and a performance reground camshaft for my L134 from Clifford Performance. I don’t see the headers on their current site but you may be able to get them to do a batch if your deal falls through. https://cliffordperformance.net/

   I haven’t installed them yet. So, I cant give any feedback.

   have them on my 62 cj6…they also reground a custom camshaft for my f-head. This is old news. Clifford, good folks…just bought intake, carb, and headers from them for my 53 gmc suburban. Call them!

   Hi Dave count me in for headers at the right price.
5. Nate January 21, 2020 at 6:15 pm

   Hi Dave, I’d also be interested in one too!

   I’m probably in depending on wagon fitment and coatings
7. Dave from Mn January 22, 2020 at 4:36 am

   I could be interested.

   I may be interested as I’m close to working on the engine part of the rebuild. Is this bolt on and go and what advantages will I get from this beside looking pretty damn good.
9. Dave Case January 22, 2020 at 5:31 am

   I am definitely interested-count me in.

    Something doesn’t look right with the number 4 tube size at block. Realistically, without a cam/header/carb combo, I just can’t imagine the impact under 4000 RPM as “significant”… besides as said “looks really cool”, and may sound different too. Some actual “performance specs” would be interesting to see range of impact over stock.
12. Scottie Ward January 22, 2020 at 12:03 pm

    Yes, I’d like a complete set as well.

    It is in fact Clifford performance that is willing to do this. They had sold out of them, but they were willing to do a special limited production run if there was enough interest. And, it looks like there is interest from the comments below (though no guarantees this will happen). This likely wouldn’t be until March at the earliest, so there would be time for planning for it. I do not have a cost estimate yet.

    years ago, there was a story on the cj3b page about the significant performance improvement on a cj3b in the Colorado mountains with the headers, weber carb, and ignition upgrade. good read.
18. David Eilers Post authorJanuary 23, 2020 at 3:35 pm

    FYI: I’ve updated the post with the news that Clifford has decided to move forward with the manufacture another round of f-head headers. I was told to check back in March. No details on the number that will be available, how much they will cost, etc.

    Here’s the link David Sapp mentioned: https://cj3b.info/Tech/KamunenEngine.html

    some of you might be interested in checking out this L-head header setup. Steve spotted it: https://cj3apage.com/Forum/index.php?topic=4538.0

    We have an update on the F-head headers:

    Clifford is in the process of making the headers. The company only plans to make a few (I don’t have an exact number). Here’s the product page: https://cliffordperformance.net/store?olsPage=products%2F134-fl-head-jeep-headers&page=3

    Hi, Interested in a header for my 1964 f head….It would be perfect. Please contact me when they will be available.. Thank you, Bill
22. David Eilers Post authorAugust 14, 2020 at 6:03 pm

    Hi Bill,

    They now appear on Clifford’s website: https://cliffordperformance.net/store/ols/products/134-fl-head-jeep-headers … it looks like you can order them today.

23. Denny September 17, 2020 at 12:58 pm

    Their website says “backordered”
24. JoeB September 17, 2020 at 4:11 pm

    I wonder if Larry would consider doing headers — or even just cutting some flanges — for the L6-226?
25. Dave Case September 17, 2020 at 5:27 pm

    I put one of these on my M38A1. I had it sandblasted and painted with VHT high temp paint.
    I had the local muffler shop install new 2-1/4 exhaust pipe and flomaster muffler. The header fit perfectly with only a slight dimple where it went by the spring shackle. Much improved top end. The zero to 50 time is noticeably faster than with the stock exhaust manifold.
    Sorry I didn’t do before and after times. I would recommend the Clifford header to anyone that wants a small boost in power.
    Plus it’s cool

    Dave,

    Thanks for the feedback. Glad to hear it worked out well for you!

27. David Eilers Post authorSeptember 17, 2020 at 5:43 pm

    JoeB … I’d contact him and ask. He might be more interested given the interest with the f-head header.
28. Scottie Ward September 18, 2020 at 7:45 am

    I recently purchased one and just received it. Quality look great. Color is black not the color as shown in the pic.
    Thanks
