Exactly pictured. 4 long & 6 of 8 needed med bolts
Called 2nd week of Jan '25 because of the picture. Talked to Richard and asked if he knew if there were 8 medium & only 2 long bolts in the package. It's pictured the same on Summit's website. But they have 8 medium bolts in their pic, on their site. That's what I needed. It doesn't matter I have 4 long bolts because I only need 2. 1 per head, 4 medium bolts & 5 small bolts per head, X2. I even gave Richard my head casting #'s & he said they'd work on my 1980 cast 2 bbl heads. But they won't, because I have 4 long bolts instead of 2. And 6 medium bolts, instead of 8. All 10 of the small bolts were in there. And I explained ALL of this to him at Jegs, over the phone & he said their system said it would work. He basically told me it was a generic pic, but it's completely accurate. What you see is what you get. And my photo shows you what you get with the help of FedEx. As a product? The bolts look good. But the washers & nuts are pretty thin material. I watched a YouTube channel called Hard Head Garage & he ordered the exact same part # from Summit Racing & he had all the correct bolts on his 318. I don't get it. I was told they'd work after I asked if someone could pull a box off the shelf & look in the package for some answers & was totally shut down, then B.S.'d into buying this product. I've never had a problem with Jegs EVER. But this felt like I got screwed. I did my research before I even called & gave him the ARP equivalent part # that had an accurate pic of what I needed. He saw it. And asked for the casting # on my head. Then he said the system said it'll work. Then told me the pic of the Speedmaster part was possibly a misrepresentation of the actual part. Disappointing. Why are companies like this now?

Poor product
I just bought these studs as I am replacing hear gaskets on my 360. They are not the correct set they included 4 of the long studs but the motor only needs 2. As a result I'm short 2 of the medium length studs. Now the project that needed to be finished today has to be put on hold until I order the correct parts from a reputable company
