Cylinder Head U20 |
Partnumber: 1152 Datsun Roadster U20 cylinder head cam tower shims U20 CAM TOWER SHIMS High Quality Aluminum. These Cam Tower Shims are precision machined, not stamped. Shims span entire width of Cam Tower. Cam Tower Shims are used to make the upper chain tight again when a cylinder head has been overly-planed. It should be noted that most of the time cylinder heads are surfaced on the bottom. However, there are times when they are surfaced on the top. It may be necessary to use our Shims in conjunction with one of our thicker head Gaskets to restore accurately the same amount of material to each side of the cylinder head that was removed. Sizes available: |

Gasket Engine Cylinder Head U20 New Products |
Partnumber: 1698 Datsun Roadster U20 Thicker Graphite Head Gasket - Intro Offer 1st photo. Nissan stock graphite gasket on the left, New thicker graphite gasket on the the right. No longer necessary to purchase, difficult to seal, all copper head gasket, steel head spacer or messy and marginal double head gasket method to compensate for overly planed cylinder head castings. Have you priced out a new U20 cylinder head these days? How about $1800.00. None of these choices are really options. We have one though! This all new gasket is .094 thick compared to the Nissan stock gasket which measures .053 at the fire ring. Why buy a thicker head gasket? During a U20 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 straightening, expensive, or a re-surfacing of both sides of the head in order for it to be flat again. Because both sides need to be surfaced the head becomes thinner. Customers and shops often correct the reduction in overall head thickness by piling cam tower shims under the towers to "get the chain tight". The problem is that this can effect the geometry between the cam and the rocker arms. Yes, this can be corrected with different U20 custom retainers that accept taller L-series lash pads of various thickness. Even with a custom retainer package this still does not solve the problem of diminished chamber volume on the head gasket side resulting in higher compression and detonation. This new gasket gives you the opportunity to correct the issue of a overly planed cylinder head by putting the height back where it was removed. Use this in conjunction with our cam tower shim sets to get the right combination. Breath back life into your cylinder head! Comes with a detailed instruction sheet and great front timing cover/oil gallery sealing information. Gasket construction and properties: High performance graphite facing, much like the Nissan stock 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: We highly recommend our U20 performance stud kit as it is superior to the original head bolt kit. Buy this gasket with our U20 stud kit and take $10.00 off the order. |

Partnumber: 2208 Datsun Roadster Smog Plug Inserts Datsun Roadster, set of four, smog plug inserts for 68 -70 1600 and 2000 cylinder heads. These inserts were reverse engineered to screw into the ports in the head where the air injectors were installed as smog equipment. They have the exact thread and contour of the injectors and fill the entire cavity; both the threaded portion and the smooth bore. This completely eliminates that annoying “chirping” sound caused by engine exhaust passing over the tube, which creates a resonant chamber (like a badly played flute). Once installed, you’ll be amazed at hearing only the smooth hum of the exhaust out the tailpipe. The clucking chicken in your engine will be dead and gone! Does not include clucking chicken. Comes with a full detailed instruction sheet. Choke the chicken today!! |
