Start with a clean slate. Strip away years of grime, oil sludge, and corrosion using hot tank cleaning and vapor honing to get your parts spotless. This isn’t just about looks—it’s about finding hidden cracks, warped surfaces, and weaknesses that can kill a build down the road. Whether it’s a classic small block Chevy or a modern LS, we clean and inspect every inch so you know your foundation is solid before moving forward.
The magic happens in the details. Our machine shop specializes in cylinder honing, competition honing with torque plates, and precise resurfacing of blocks and heads. We restore perfect bore geometry for proper ring seal, boost compression consistency, and eliminate the hot spots that lead to detonation or power loss. We square deck blocks, true crank bores, and set bearing clearances to exact specs, ensuring your engine spins freely and makes the power it’s supposed to. It’s the difference between an engine that simply runs—and one that sings at redline.
When parts are damaged or worn, we don’t just replace them—we fix them right. Broken bolt extraction, cracked block repairs, valve guide replacements, multi-angle valve jobs, and port matching are all part of our daily grind. We balance rotating assemblies for smoother, safer high-RPM operation and polish crank journals to like-new condition. Whether you’re chasing big power numbers or restoring a piece of American muscle history, our machine shop work is driven by precision and a deep respect for the craft. At Green Mountain Gear-Heads, your engine isn’t just a collection of parts—it’s the beating heart of your ride.
Green Mountain Gear-Heads primary focus is on domestics, but can sometimes support non domestic builds.
