Horsepower and Head Gasket Technology
Head gaskets have one of the toughest job in an engine, and now we’re pushing them harder than ever, making it easier to expose the slightest weakness.

High Horsepower Engine Sealing
In the context of high-horsepower engine building, the pressure on a cylinder head can be so great that it can, in effect, marginally push it away from the engine block. This makes engine sealing one of the more prevalent challenges, and it gives whole new meaning to the phrase “keep your head down.”
Copper vs. MLS Gaskets for 1,500 HP
For a 1,500-hp capable engine, should it be sealed with copper or MLS gaskets?
SCE Vulcan Cut-Ring Head Gaskets
New SCE Vulcan Cut-Ring head gaskets are designed for use in engines with high static compression forced-induction or nitrous oxide where typical composite or MLS head gaskets may be prone to leak combustion pressure and-or coolant.
Diesel Performance Head Gaskets
The stock head gaskets that are used in most light truck diesel engines are robust enough to handle peak combustion pressures in the 1800 to 2200 PSI range, but may not do so well at higher pressures if the engine has been tweaked to produce more power.
Fel-Pro Diesel ML7 Head Gaskets
Sealing the most demanding area in an engine takes today’s most advanced gasket design. The ML7 design provides multi-layer-core head gasket technology that significantly improves combustion and fluid-sealing capabilities, and heat resistance for a broad range of high-output commercial diesel engines.
Head Surfacing and Straightening
Clean, smooth and flat have always been requirements for proper head sealing whether you are building a stock engine or a monster motor for a ProStock drag car. Head gaskets can only accommodate so much distortion and roughness across the face of the cylinder head and deck. Resurfacing the desk surface on a cylinder head and/or engine block should restore flatness and achieve the required smoothness.
