    I believe i know the answer but wanted to verify. is it just the stage blocks that have the 14 bolt holes for heads? Or can you use the 14 bolt aluminum heads on any production grand national block? Thank you in advance for looking

    14 bolt works on the stock block.

    There are 2 "stage" blocks and one may have the 14 bolt heads. All of the "stage" blocks can be drilled and tapped for 14 bolt heads though.:) Might want to check out www.gnttype.org for more on block design and heads.;)
