I was torquing down the new Victor jr. heads
and was using Anti seize on the bolts. As I torqued the las bolt to 60 ft. pounds I felt that sickening feeling of the wrench getting easier to turn! Yep pulled the threads.
So I went and got a repair kit with tap,installation tool ,29/64th bit and heli-coils. I was lucky enough to be able to reach the stripped hole good with the motor still in the car ,so I carefully drilled, cleaned ,tapped the hole and then installed the heli coil and left it alone for the night so the lock tite could dry. Well today I went to install the heads again and found that I put an angle on the hole I drilled!
Not enough to see until you put a bolt in and realize it is binding against the head.The only thing I can think of to do is have a Larger hole drilled "straight this time" and use a Thicker thread insert(heli-coil)Any suggestions from you guys would be appreciated...By the way I have already removed the helicoil from the hole without damaging anything.------------------

I would reinstall another heli coil and them put in a stud. You can then tap on the stud to straighten it out.  ------------------

If I get a set of ARP head studs are they "bendable " enough to tap into the desired angle without breaking? I would have thought that they would be very hard,and if I did do a little bending they might just snap? Or should I use a slightly lower quality stud like Maybe Milodon????

Milodon is fine. A stud will bend at the threads.------------------

Check McMaster Carr, they stock angled washers, for just such problems.------------------

Well I got the new heads on,I used a stud and "tweaked" it until it was aligned right then just bolted the heads on. Special thanks to local legendary Ford drag racer Steve Berkner for seeing my post here and donating the head studs needed!
