Started a new ls7 build. Dart ls next pro block and Frankenstein f710 heads. I purchased Arp 23 bolt head stud kit from Dart. I install the studs in block no problem. Install the 4 studs in the bottom of head no problem. Mated the 2 together then start the torque sequence no problem. Once I got to the last 4 studs to torque which is the studs that's in the bottom of the head. I noticed a couldn't put the washer on. I could barely put the nut on the stud using 2 fingers. The location of the nuts and studs is in the lifter tray area. There is no way I can get a torque wrench, socket or regular wrench around the bolt to tighten it. At best I may be able to use vise grip pliers to tighten it. Has anyone run into this problem? Is there a fix? Any help will be greatly appreciated!! Thank in advance!!

nut is too close to cylinder housing

grinding down the box end of a wrench was the only way i could get anything on them and be able to tighten them up. didnt really worry about torque

Its almost like and allen head bolt would be a better idea. The tool above KCS looks good. That being said I also have seen ARP makes a nut that is even smaller but not sure what threads you have there. I used it on some carb studs I had where the normal was say 7/16 12 point and they made 3/8 12 point for a 5/16 bolt.

If they are 3/8 studs for a 6 bolt head kit arp(btr kit) they come with a thick washer for the bottom of the heads/and a thinner washer for the lifter valley. get you a 3/8 wrench and grind it down(the box end )use the open end to install 3/8 torque wrench in. and when using the torque wrench make sure you are using the right way.were your tightening upwards /flip the torque wrench over to make it tighten Clockwise .hope this helps

If using the took that KCS mentioned, which IMO is he right tool for the job, there is a little bit of math involved to achieve the correct torque spec, IIRC
