Cylinder Head G15 R16
Datsun Roadster 65 - 70 Thicker R16 1600 Head Gasket .120
No longer necessary to use a all copper head gasket and the different challenges in making it work. Also not necessary to double stack two stock gaskets and pray for this method to stay sealed.

Why buy a thicker head gasket? During a R16 cylinder heads life span it can be surfaced many times to the point where the head is nearly unusable. If your head has been overheated and warped it requires either oven straitening, expensive, or a re-surfacing of both sides of the head in order for it to be flat again. Thinner cylinder head castings have a serious problem of diminished chamber volume resulting in higher compression and detonation. If you are using dome pistons mechanical interference with the valve pocket will lead to either small end or big end rod bearing failure. The valve pocket can be professionally and carefully machined, at an additional cost, so as to provide mechanical clearance for the pistons, but this does correct the problem of subsequent and undesirable higher compression.
We recommend that you purchase a tube of the special silicone we sell part#2402 help seal the rear oil gallery of the cylinder head gasket
Gasket construction and properties: High performance, high density composite, graphite facing, much like a Felpro gasket, on a perforated carbon steel core. Stainless steel fire rings installed at each bore. Graphite has excellent sealing, conform ability and high temperature resistance.
NOTE: It is highly recommended that you use our R16 performance head stud kit when installing this gasket as it is superior to the original head bolt design.
