so I bought a set of 70 valve covers from AMD. Ive been wanting to put up my before and after pics of going from 4 to 6 pak. Yesterday I decided it was time to install the valve covers. Driver side was a little tough but not to bad. So I go to do the passenger side and I was fighting to get 3 bolts in so I walked away. This morning I spent 2 hours and even opened the bolt hole 1 size up. Well it still would not go on. Ended up putting the old set on and it only took 1/2 hour. A member here had 3 sets for sale and I passed because I wanted to have a new set. Guess I learned a lessen dont pass on the original stuff if you dont have to.
