I have a new set of Mummert aluminum heads. They are going on a stroked and bored y-block with a healthy cam. I would like to use roller rockers. I have seen references to various rocker companies on this forum but when I go to the websites I see nothing about roller rockers for a y-block. Am I missing something? Will later FE roller rockers work? Thanks.

Thanks you for the answer. I will follow up with an email.
