I think I did a foolish thing this weekend. I used a 10Mx1.5 tap (Snap-on) to clean out the head stud threads of any old loctite that might still be in there before I install 12 replacement steel studs. The tap threaded in with only mild resistance and didn't appear to be removing any metal in the process (or I'd have stopped immediately), so I wasn't initially concerned. Afterward, I tried threading in one of the old Dilavar studs and it threads in with no resistance at all.
I'm sure the studs need to be a snug fit into the case and I'm angry at myself for doing this without checking after the first one (I know better)...
Have I screwed up (no pun intended

)? Is this an acceptable condition, or is it a problem? Can I simply install the studs with fresh Loctite, or should I have threaded inserts installed? Is there any other compound (other than loctite) recommended for use to install the studs in this condition?
Btw, this is a '79 3.0 Alum case.
Thx, Mike
