Where did the idea come from? 

I have tried every head gasket on the market for our engines and always had some sort of problem in my Mazda BP 1.8, pushing water due to the head gasket not being up to the job. So then I went to a bronze fire ring with copper gasket, like all the big power drag and time attack cars use. The problem here is that I had coolant weeping issues out the side of the block when the engine was cold because the copper shrinks, then expands when hot. I asked around a few of the big engine building shops to see what they do to seal the copper properly. Some say it doesn’t worry them because they pull the engines down so often and others say they use black sealant on the copper, but be really careful that it doesn’t squeeze into your oil or water galleries… this is what made me start thinking that there has to be a better way!

I wanted the bulletproof strength of the solid bronze fire ring for the high cylinder pressures, but an easy seal solution for the low pressure oil and water galleries. So I came up with the idea of using a dense composite gasket material with silicone/sealant embossment around every water and oil gallery. This will not only create a pressure seal around the galleries, but also an adhesive seal once the head is torqued down, so if for any reason you do get movement or a micro lift of the head, into a water or oil gallery is not the easiest route for the combustion pressure to go.

​

Put this with the solid bronze CNC machined fire rings, you near have a bulletproof head gasket. Far more superior than an MLS gasket, which has more layers to fail on and relies on dimpled layers and folded tin to create the seal. A standard composite gasket creates the best seal around water and oil galleries because it’s ability to flex and move with the head and block, but the folded tin fire ring is what makes them weak.

I fitted one of our head gaskets to my engine (which is run under a lot more stress than most). In the Sydney 300 last year. This was the first time I have not pushed 1 ml of water into the overflow and the car never got hotter than 89 degrees the whole race! Since then it has done 3 more race meetings without an issue.

I believe i have completed my mission in creating the most advanced and reliable head gasket on the market and look forward to helping you avoid those continuous head gasket issues!
