Call noss machine up. He probably has the set of domes that your looking for on hand. Standard domes, big bore domes, standard bore stroker domes, big bore stroker domes, domes for running 4mill crank with blaster pistons. He would be the guy to tak to. Talk to the man that makes them rather than the guy that just sells them. Plus he is a site sponcer and a good guy to deal with.
