some pics of steel squish head
inserts designed and manufactured by Pascal Benoot in Belgium
A unique and inventive way
to deal with the problem of cracked heads and getting squish heads out of
a standard head.
"the temperatures are good; but in the
beginning I had problems with the cylinder head gasket, the problem
was that the original gaskets are in aluminium and the coeficient of
tension is not the same of the metal head and the cylinder.
Now I use no gasket but just a copper paste of
permatex (copper spray a gasket) and all the problems are gone."
