Roller valve lifter anti-rotation guide

A roller valve lifter anti-rotation guide for internal combustion engine valve lifters reciprocally mounted within an engine bore along an axis and having a pair of substantially parallel spaced flat surfaces defined thereon adjacent a valve lifter end and radially spaced from the lifter axis, comprising, in combination, a body molded of a heat resistant material, engine mounting means defined on said body for mounting said body on an engine adjacent valve lifters to be guided, an elongated socket defined on said body having an axis and adapted to receive the end of a valve lifter having the flat surfaces defined thereon, said socket including and at least being partially defined by a pair of spaced elongated fingers having internal flat surfaces defined thereon in spaced opposed relationship to each other, the spacing between said finger's internal surfaces being substantially equal to the spacing between the valve lifter flat surfaces whereby said finger's internal surfaces engage and receive therebetween the valve lifter flat surfaces and prevent rotation of the valve lifter about its axis.
