Product Details

The Cometic C7989-EST is a complete top end gasket kit designed for Honda engines with a 55mm bore. This comprehensive kit utilizes Cometic's Extreme Sealing Technology (EST) to provide superior sealing performance and reliability in demanding conditions.

Extreme Sealing Technology (EST):

  • Embossed stainless steel head, base, and rocker gaskets covered with a proprietary rubber material
  • Advanced head gasket material draws heat away from the combustion ring and dissipates it evenly across the gasket surface
  • Eliminates hot spots and prevents gasket failure due to thermal stress
  • Superior sealing performance compared to traditional multi-layer steel gaskets

Complete Top End Rebuild Kit:

  • Includes all necessary gaskets, seals, and O-rings to rebuild the top end from the cylinder base upward
  • Precision-engineered for 55mm bore applications
  • No need to source individual components—everything required in one kit

Cometic gaskets are trusted by professional builders and racers worldwide for their exceptional quality and performance. This EST kit provides the ultimate in sealing reliability for your Honda engine rebuild.

No bad. Could indicate line size, like 5/16 in. I had to lookup Dorman's P/N to find the size. Tks

Didn't see military/LEO discount =(

I hope this time there will be no problem or cancellation of my order from your end, as I confirmed the stock from your sale department personnel (Hector) before I proceed on checking out.

Autoplicity has the best prices and customer service. The online chat is a great function to get more information about an item. Also they had an item in stock that I couldn't find anywhere else.

shipment came very speedy and everything was exactly as expected. All parts were in excellent condition.

Autoplicity had a MSD Timing Twister that was discontinued and no one had in stock. I called 6 places before getting in touch with them. Ordered part and had it in a matter of days.

Best price, easy purchase now lets see how quick they are on shipping.

all went smooth with check out now to see how fast the shipping concludes..

Easy to use website, would use again. Had the hard to find part I needed.
