SCE Pro Copper Head Gasket Toyota Supra MKIV Lexus SC300 GS300 IS300 2JZ-GE 2JZ-GTE 0.050" 1.27mm

Not all solid copper gaskets are created equal. SCE uses premium 99% pure copper sheets rolled to our specifications (choice of 12 different thicknesses) and tested for uniform flatness to assure precise cylinder head-to-block alignment and eliminate uneven loading. After processing, each gasket is annealed to ensure optimum mating and provide measurable gains in cylinder sealing, as evidenced by lower leak-down percentages. O-ringing recommended.

*Recommended uses: Extreme Boost, Nitrous, Blown Alcohol or Nitromethane.

For best results SCE Pro Copper Head Gaskets should be used with O-rings in the block or head and sealant if liquid cooled (use Copper Coat, SCE p/n G1612).
