interesting valve design

this is just something i whipped up on big blue saw designer. what do you think? the bolt holes are marked green and its assembled layer by layer(layer numbers at bottom.) i designed it for an engine but you could use it for a semi auto valve <a target="_blank" href="http://h.imagehost.org/download/...
