This is a quick random question about my valve cover
I didnt want to start another thread

are ALL the bolts used to attack the valve cover to the head the exact same?
for some reason, after I put the new cover gasket in, and tried to put the cover back on, one side ALMOST all the bolts tighten, the other NONE of the bolts tighten
can you guys help me out with this one?

SORRY TO ASK SO MANY QUESTIONS
but ya'll are truly VERY helpful

THANK YOU
