[Description] Partnumber: 2270 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. 1ST photo. Stock thickness gasket on the left. New thicker gasket on the right.This all new gasket is .120 thick compared to the Nissan stock gasket which measures .053 at the fire ring. 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.This new gasket gives you the opportunity to correct the issue of a overly planed cylinder head by lowering the compression and by providing adequate clearance between the pistons and the valve pocket. Includes a instruction sheet. 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. [Price] $218.00 [Categories]
