Are you tired of dealing with subpar cylinder heads that just can't handle the heat? Look no further than our brand new and fully loaded C13 Cylinder Head. Our castings are engineered, designed, and assembled right here in the U.S.A. and are of better quality than OEM. With 5% more nickel content in the casting material, our cylinder heads are built to last and prevent cracking between the valves. But that's not all - our coolant passages have been enlarged by 30% and inner ribs have been reinforced to reduce heat stress. And if you're really looking to take your engine to the next level, our Stage 2 Cylinder Head is the upgrade you need. With upgraded inconel valves, you can rest assured that your exhaust valves can handle higher temperatures and pressure without the risk of fractures. Don't settle for a standard cylinder head that's prone to corrosion, pitting, and cracking. Upgrade to our superior quality cylinder head and get more out of your engine. Trust us, you won't regret it.
