ke70dave Posted August 24, 2011 Report Share Posted August 24, 2011 forging most likely woulndt be much of an advantage anyway in a cylinder head or block for that matter. in a modified factory engine anyway. the head is only dealing with the pressure from the cylinder (+water/oil galleries), which is quite high, but not that high for a lump of steel/alloy to resist. it is the components that need to resist high speed, high temperature, very quick changes indirection, very large forces. ie rods, pistons, cranks. That forged materials may allow more reliability. 1 Quote Link to comment Share on other sites More sharing options...
