Torx Injector Bolts

So...

Chased down all the vac. leaks I had and during a short jaunt, engine started running lean again. Working on removing injectors to track down potential fueling issue, but previous folks torqued the bolts down to god knows what. The last bolt I have to get out is firmly stuck. I've beat the Jesus out of it with a hand impact, no avail. even after ~a week of getting soaked in penetrant. Broke down and threw the bit on an air impact -- broke the bit. I'm a few steps away from deciding it just needs to be drilled out.

Before I go that far with it I was wondering if anyone happened to know the specs of the bolt so I can search for a replacement, preferably not of the torx kind, to throw on there when putting everything back together.

Thank you, once again, for the help guys.

 

converting the torx to studs and nuts is pretty common. screenshot yanked from another website.

 

Also, you'll need to cut off the conical washers from the OEM bolts.
