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.
Head Gaskets and Fasteners
The relationship between head gaskets and head bolts is an intimate one. The clamping load applied by the head bolts is what allows the head gasket to maintain its seal. For this marriage to last, there has to be constant tension – not too much, otherwise the bolts may stretch or break, and not too

Fel-Pro PermaTorque Head Gasket
Fel-Pro PermaTorque LaserWeld stopper layer design was first developed for Professional Stock Car racing engines, and is now available in Fel-Pro PermaTorque multi-layer-steel (MLS) head gaskets for a broad range of late-model automotive engines. The new LaserWeld combustion seal ring provides a precisely determined and controlled limit to the compression of the multiple layers within
