Save yourself time, money and frustration.This place is a real piece of sh*t! I sent my heads to them for a simple valve job. (The #5 cylinder had burnt valves but the other cylinders were fine. Of course, we agreed to do a complete valve job to all six cylinders.) I was told by Cody "two to three days at the most." After a week, I had to call them to see what was going on and was told that the mechanic was having "personal problems" so he wasn't able to focus on my heads. After another week of waiting I was told they were done and ready for installation. After the garage reinstalled the heads, the car ran worse than when it was brought in. Cody had the garage mechanic "try" several stupid fixes and finally the heads were removed and inspected. The mechanic poured water in each cylinder and one cylinder from each head was leaking so the heads were sent back to AEM to be properly done . So what does this idiot do? He takes a picture of some other head he had in the shop, that had a huge gouge in it, and claimed it was mine and that it was foreign object damage caused by the shop. Nobody saw this obvious gouge when the heads were in the garage. Cody claimed he resurfaced the damaged head and replaced a damaged valve, all for free, even though it wasn't his fault. Bullsh*t! This took another week. When I finally got the heads back again, I had a friend who builds race engines, do a vacuum check before wasting time with another installation and removal. (This is something every decent machine shop does before sending the heads out.) The same two cylinders wouldn't hold the vacuum. This clown had held on to the heads for a week and didn't do anything except blow a bunch of lies and B.S. out his ass! My friend offered to do the heads after he was done building two engines he had already contracted to do even though he doesn't do street engines. After a couple of weeks he was able to do the job and the heads were reinstalled. Due to AEM's lack of professionalism and sh*tty craftsmanship this simple two day valve job cost me five extra weeks and an extra $750.00. Beware: This place sucks! If I could rate them with negative stars, I would. read more
