Arias Cylinder Head Shop

Been coming here for years.. johny is your man when it comes to performance he young but was…read morethought by oldschool mechanics has done 2 of my blocks and 2 heads and are running strong highly recommend this place ..

I haven't needed any machine work in close to 40 years, so I had to search to find a machine shop…read more My buddy found this place and called for a price, which seemed pretty fair. We tried calling a few others. but none of them answered. THE GOOD: This is an old school machine shop that works on more than cylinder heads. Two brothers own the shop and one of the owners son, Johnny, is awesome, very communicative and a really nice guy! The prices they charge "seem" to be very reasonable (I have nothing to base this on). THE BAD: This is an old school machine shop that works on more than cylinder heads. 1. They are VERY old school, to the point that their system for tracking "what parts belong to who" consists of your name & number scribbled on the back of a business card that is stuck into an opening in whatever part you dropped off, nothing else. 2. Out of the 6 guys that work there, only one, Johnny, speaks English. 3. The phone rarely gets answered. 4. It looks more like a scrap yard than a machine shop: (literally) tons of cylinder heads, engine blocks, crankshafts and camshafts, etc everywhere! THE REALLY BAD (in my case): They called me about 11 am to say my heads were ready to be picked up. As I was busy, I didn't get there until around 4 pm. I walked in, speak to Johnny and let him know I was here to pick up my small block Ford heads. He looks... and looks... talks to another guy there... and looks, then makes a phone call. He then tells me, "a guy was here about 10 minutes ago looking for some small block Ford heads and they gave him your heads and he will be back in about 10 minutes". WTF?!? It was more like 20 mins, but FORTUNATELY this guy pulls up with my heads in the back of his truck. Johnny did apologize a few times about the confusion. I comment on how disorganized they are and he apologizes again. I pay my $240 (no courtesy discount), I thank Johnny and leave. THE VERDICT: Obviously their error was corrected after the guy who had my parts returned them. I'm hoping my experience is a very rare occurrence and no one else has to go through this. Otherwise my cylinder heads were machined as I asked.

Have used them in the past and although it came out higher than expected, they were transparent,…read morehonest and cordial. Fast forward to this instance where I have a batch of rotors that I needed to be turned down 1mm each side. Call him, describe what I'm needing and ask if he has a rough estimate on price. He asks me to text pictures, I jot down his number and then send him pictures shortly after. Gave him an hr or so and called him back to see if he received the pictures. Doesnt reallt acknowledge it and is pushy to have me bring them in and that he can do it. I'm about 25ish mins away, but he insists that he'll be late at the shop and that it's no problem. I bring in 1 rotor to see if he can still give me an estimate and he suggests he can help me bring in the rest of the rotors, about 10 in total. As we're bringing them in, I ask him again how much he's thinking it's going to be and he mentions $50 each. At this point, it's beyond the threshold in which the supplier was going to reimburse me for so I ask if I can just machine 2 rotors for now and figure out what can be done with the supplier. The next week rolls around and days go where I dont hear anything. I text him and no response for a day or 2. I call later the following week and he gives me a response like the rotors have been done and that he's been waiting on me. I ask him texting is the best method of communication since he originally asked me to text and he said text is good. I ask him if he's been receiving my texts in which he responds with affirmation. I go to pick up the rotors and come to find out that he only did a single rotor in which I ask when the other side would be done and he says in about 1-2 business days. I say that's fine and then mention that I'll leave that single rotor behind and grab the rest. He then mentions that if I in doing just 2 rotors, that the price would be $100 each. At this point, I'm no longer feeling like this is about money and get the impression that he's just a shady crook now trying to take advantage of people. I'm a little shocked at the pricing at this point and ended up just taking all the rotors back and paid him his $100 to machine a single rotor. Ended up having another shop do the for $20 each

Great work and quality customer service from start to finish. Everything you need from a business.read more
