jagwit Posted November 21, 2012 Share Posted November 21, 2012 Hi all Simply by using the tin gasket (0.4mm thick I am told) as opposed to the composite gasket (1.2mm compressed I am told) will up the compression on a "high compression" V8 from around 9.4 to around 10.3. Doing so has the additional advantage of not having to use the 20Nm, 90deg, 90deg head torqueing regime but only 90Nm per bolt (as per RAVE - which I think is too little). The benefit is the MUCH reduced stress this puts on the threads in the block which serves to "preserve" the block for future rebuilds. What is so bad about the tin gasket that it should be used?
