FWIW I got this from Yellow Bullet,
The studs were never arp. I worked on the original hemi/wedge blocks from world and I pointed out to Bill Mitchell about the studs and he did not answer my questions. I would put the main studs in finger tight and they would still feel loose. You could wiggle them with your finger tips. I never did like them. Kenny.

Yes as this will cost way more to correct after the fact than the cost of the arp studs.

I see now that the cross bolts on my engine are ARP. With the stud nuts saying ARP, and the cross bolts being ARP, why would we have questioned the studs manufacturer ? An easy way to deceive us. I would have gladly paid up front for the ARP studs. Like said, it would have saved a bunch of time and money in the long run.

I have a world iron block that was purchased in the Fall of 2009 and assembled by Dwayne Porter and subsequently dynoed (720hp/720tq)...it's a pump gas 572. When this post came up i spoke with Dwayne and he stated that the main studs on mine torqued up fine. He stated that the studs are good and not to worry about it. This is not a full on effort and if it were i would have better hardware in there anyway....including the crank & rods. Perhaps World has changed suppliers in the past year ? That could certainly account for the soft metal fastner that a few of the reputable engine builders have described. Ron

I got a WORLD hemi cast iron block YESTERDAY and it has the non-ARP suspect studs. They will be replaced with ARP hardware. Good luck.

I still believe there are motors out there that people simply didnt " catch" this problem. Between inexperience, in a rush, "thinking" it didnt feel right but using them anyways, not knowing, or lastly just not caring, they are out there.There seems to be some that may be different or ok, just dont know when.
It would have been very easy for some to just use them and not really know what they were experiencing.The design of the bad studs is just that, bad. No comparison to the rolled ARP threads, undercut, chamfer etc, not taking into account the actual tensile strength , hardeneing or overall soundness.
I have already changed out several "studs only" for the mains, as well as gotten new complete kits for members here and my own clientelle. I think if nothing else, they all are resting better. The " bad" ones really are BAD.

OK, I have done some research on these main studs.If you already have the ARP cross bolts and ARP nuts on the "no name" studs, you can replace the main studs with ARP #AR4.620-1LB X 8 and #AR4.400-1LB X 2. I did a google search and vendors have them for aprox. $5.50 each.

That is correct, and your part numbers are correct. I posted way back in the post the part numbers for new stud kits. I dont think the side bolts are of any issue. Everyone can make up there own mind, make their decision based on whatever it is thats important to them, and move on. I am burying this dead horse from my perspective, because their still seems to be people that dont believe this is an issue or dont believe the findings. We all have our own opinions and choices. Good luck to all.
