I know this has been covered but my bolts aren't threading in nicely into my block after having it on the stand, and I wanted to clean the holes up on the block to the bell housing and everyone says its M12 - 1.75 and I have a tap thats that size but it seems like its a little too bit and its going to make the hole much bigger causing my bolts to not fit.
