Amidst the rise of big automotive suppliers, there are still mom & pop shops that are committed to serve the automotive community. One of them is American Cylinder Head, Inc. As the company name suggests, it churns out remanufactured cylinder heads in its ISO 9001-209-certified Oakland, California facility. The brand offers a vast selection of remanufactured cylinder heads ranging from the Japanese Toyota 4AGEs to the American Chevy 350s. This was also a good opportunity for us to see how well the American Cylinder Head cylinder heads can be. We got heads for our 1969 Chevrolet Camaro RS equipped with a small block 350. Now, the 350 is a sought after engine in the restoration scene. Our test would determine how much horsepower it could create while sticking to the original componentry as much as possible.
- New springs and valves included
- Pressure-tested to ensure leak-free casting
- Limited warranty: 1 year or 12,000 miles
- Our '69 Camaro was due for a top overhaul. So while we were at it, we grabbed the opportunity to test the remanufactured heads from American Cylinder Head. The current parts that went along with the 350 included a mild cam, headers, and a four-barrel carb. With the Edelbrock heads that we overhauled, our Camaro can make over 300 horses. After installing those from American Cylinder Head, we placed the Camaro on the dyno and it still made roughly 300 horses. That's understandable since we're using Edelbrock performance heads previously.
- Remanufactured heads cost significantly lower than brand new aftermarket heads. We bought our Edelbrock heads for roughly twice the price of the heads from American Cylinder Head. But then again, we got the Edelbrock heads so that the Camaro can run faster.
- American Cylinder Head remanufactures heads to factory specifications. While this is good for people who like it stock, it did not sit well with us. We were hoping to find a set that could at least tickle our need for an extra oomph.
The American Cylinder Head remanufactured cylinder heads are ideal for modest engine rebuilds. If you're after a factory spec Sunday driver or maybe even a day two car, then this could be a viable option for you. However, if you want to squeeze out all the horsepower you can get from your engine, then this might not be the right head for you.
