COMPETITION HEAD GASKET

[demime 1.01d removed an attachment of type image/jpeg which had a name of d1c829838444988d7b55e05ed0b7db0f.jpg]
The very latest design using modern manufacturing techniques means  
this three layer all steel gasket is the best on the market. It has  
been made solely for us on dedicated tooling at considerable expense.  
Whether used on high compression race engines or simply to stop the  
constant water leaks down the distributor side of a standard engine,  
this is more than adequate to do the job. Being the same thickness as  
original it does not change the compression ratio and suiting bores up  
to 3.562" (90.5mm) diameter. This gasket may also be used up to three  
times.
