Over heated the Engine twice and am Removing the Cylinder Head; likely warped.

I am using a US made K-D 2603 in the attached picture (KDT2306 Features: -Install and remove 12 point (triple square) metric socket head screws with these tools. -Made from heat-treated alloy steel. -Turn with socket or wrench. -12mm Serrated Wrench. Size: -12mm.) Which I bought when I overhauled my Volvo Diesel Engine way back.

When I put the Tool in a 1/2 inch socket it has a overall length of about 4-5/8"

The problem I am having is it worked fine on all but 2 of the bolts. I need to use 2 hands on the end of the breaker bar but the bolts are so tight that the length of the tool+socket cause it to cock. If I had a third arm and hand to keep it straight it would work.

I hate to do it but I am going to cut the tool short so the over all length will about 2 inches. I hate to do that to a US made tool.

I am wondering if someone else has had a similar issue.

I ordered another one on eBay where they are fortunately only around $6 each (K-D Tool 2603) But the replacement is likely to be made in China.

The original Mercedes tool (Mercedes number 617589001000 617 589 00 10 00 144mm long) is even longer and would have the same cocking issue if I used 2 hands on the breaker bar handle.
