Super easy and quick machinist! Had my 5m-ge head from my Cressida taken over there for him to check out. Came back super clean and with great results!

This is the best machine shop in northwest! I need it a mainline done on my Subaru ej25 and this is the only shop that was able to it on their state of the art CNC machine! If you need any machine work done bring it here, you wont regret it!

This is the only machine shop in PDX that I trust to touch my high horsepower EJ25 engine builds. Several hight horsepower engines are built with the help of their machining service, all engines run flawless and without any problems. G&A you have a customer for life!

Good work. Quick turn around. Reasonable pricing. State-of-the-art equipment.

We Are Very Happy Having work done here. He is Honest, reliable and Reasonable. We would recommend Gerardo to anyone that needs machine work done. He Did the Work On This Engine.

Awesome machine shopQuick turnaround and good prices

Would not trust taking my head or bottom end anywhere else. The owner of G&A knows his stuff, and he will recommend you the best parts for whatever build youre going with, that is also cost efficient. Few of my other buddies have also taken their head and blocks to get work done by G&A, 0 complaints.

We had a pair of cylinders resurfaced and a bolt extracted from each side. On one of the sides somebody had previously tried to drill out the hole and didn’t get a center hole. When G AND A tried to repair the damage the flange broke off and they replaced my head free of charge. Absolutely wonderful service. Will be returning with future work!

Needed to surface a flywheel for one of our tow trucks, G&A was able to do it within 15 minutes, at a reasonable price, and with a smile on the face. Will back for any machine work in the future!

Vary fast and vary reasonable prices

Came down with 2 cylinder heads and both were machined right in front of me showing me the warpage on the heads, these guys are the best, most professional machine shop you can go too!$40 for machining + wash is outstanding.. you cant find that price ANYWHERE! If you need any machine work done go straight to G&A or youll be sorry!

Brought in cylinder heads from an 06 Nissan Murano and not only were they very familiar with the heads but they also gave me some suggestions on what else to look for, they pressure checked and resurfaced the heads they did a phenomenal job.

Very helpful. Broke off a rocker arm bolt in the cylinder head of a 1991 Explorer brought it here and service was very prompt and they got it out no problem. Will definitely be coming back if I need more machine work in the future.

Thank you Gerardo and Martin for the awesome workmanship on rebuilding the head and engine on my six cylinder 200ci engine. The engine had piston slap on # 2 cylinder. The engine purrs like a kitten. I highly recommend this company for any work on engines. A true professional in their craft.Thanks again,r/Nick

Gerardo is great! Very friendly and professional, needed to check cylinder to wall clearances for my new Subaru block for forged pistons, he was happy to help. He also showed me few customer projects he was working on. The shop is very clean and organized, would definitely recommend him to anyone and definitely will be back in future. Thank You!

This guy is one of the smartest engine men I have ever dealt with.No matter what head I bring he always knows what needs to be done.His prices are excellent and work is quickly turned around.

This place is great and I wouldnt hesitate to go back. I brought in my two Subaru WRX heads for a refresh. Gerardo was great explaining the whole process they go through and gave me a tour of the shop. The work done was very high quality - I got all OEM Subaru valves, new valve guides and seals valve lash set, heads cleaned and decked. When I wanted the valve lash changed from the spec (which varies for 02-05 2.0L models) Gerardo was happy to oblige. On top of all this, pricing was very reasonable.I would definitely recommend.

Wow! Amazing customer service. Very friendly and responsive to my individual needs. Fast turn-around, and exceptional work. G&A has gained my respect and confidence to do great machine work. Would definitely recommend to anyone looking to find a machine shop that they can trust!

Gerardo is very detailed oriented ! Great communication throughout my builds. He takes his time to go over everything !

Great and friendly service and great pieces.. I shopped around many places and these guys had the best response time and the best prices.. And the work was amazing. Thanks

Gave him my cylinder head off my Honda trx 450. Did an awesome job! 110% recommend.

Excellent machine work. Gerardo is patient, meticulous, and highly skilled at engine rebuilds.

I happy i found this machine shop rebuild my ls heads. NICE CLEAN SHOP NEW MACHINES, not like D&D didt fixed my heads right.

Awesome service and attention to detail. Shop was clean and service was great. No BS, just fast work. Really pleased.

Currently have had 3 different long blocks completely rebuilt. A straight forward HONEST machine shop who does your blocks CORRECTLY to spec. Always uses new part with fast and friendly turn around.

Highly recommend Gerardo for this type of work i put alot of money/Faith in Gerardo for my first motor build on my vq35de. he treated me very well, great work, lots of knowldge and was not afraid to share.

I had a total build on a B18C1 head including the port and polish. I was very happy with the price i got, and the quality of work shows. I recommend G&A for anyone looking to rebuild there cylinder heads!

Great place to have your cylinder heads done. Great service and quick turn around time, more like next day service. Glade I herd about you guys.

Very professional and timely. Very pleased with the quality of his work and customer service. Would recommend to others.

These guys are great, they do amazing work and quick return time. They fixed 3 cars for me and they r always honest.

Awesome service. Went above and beyond to help me fix my car. I will be using them again.

Great service and super easy to deal with. They saved my bf a great deal of money and same day service.

Thanks for taking care of me on the fast service. Will recommend u to everyone I know

This is the place to take your heads for service. I googled a place and used a shop named Dans Cylender heads and they did my Subaru heads and they still had valve leaks.. The mechanic shop charged me labor twice because the other place didnt do their job right, so the service shop I used recommended G&A cylenderheads which was very close to the shop I went to. Needless to say G&A had my heads done same day service with no issues.. They sure earned my business in the future.

Great service and fast service. Doesnt get better than same day service.

Professional work.

Great service 👍👍👍

Their guaranteed jobs and the great organization and cleanliness of their work area, which undoubtedly says a lot about the quality of their work highly recommended.
