I bought a set of AMS rods from their eBay store "Buy AMS". The rods were too wide to fit into the top of the cylinder when assembling my motor so I notified them. They said I would need to shave them down slightly for them to fit. Now had the description with the rods stated this I would have bought others and been done with it. After shaving quite a bit off of the rods 2 times they still don't fit. I notified them again that this didn't work and they told me that another customer had to shave them and they worked no problem. I'm at the point where if I take anymore off I would not feel comfortable running these with such little material left around the rod bolts. I would not recommend buying these rods regardless of price. You get what you pay for and that's what I did. I am buying eagles now.
