This stuff isn't new, Marco's been building 2.1's since 2001. And there's actually quite a few people running past 10k on various DSM motors, pretty much anyone in the 9's or better, which these days is a lot. And our heads flow plenty for 10k usage with mild work. You should see what it takes to get a stock 350 Chevy head to flow anywhere near what ours will.
