273 rockers arm lock kit

I bought a set from Mancini Racing for way to much money. Got them in and they do not fit I don't think. I know they should not screw in easily but I broke an allen wrench trying to get one in. I did buy some lock nuts as well that I'm going to try and return what I bought from Mancini. I am going to try and remove the lose adjusting screws and install just the nuts I have. I only have a couple that I would call loose. Hoping to get it wrapped up for the cam break in Friday since its an off day from work.
