i might talk with Zach about this first.. his port design isn't of conventional design for deisels and leads me to believe as he himself proclaimed early after the release these heads are oriented toward rpm, and not low rpm spoolup.. i havent heard much talk about it. I also cant say much i just bolted mine on today so sooner than later i will know how well it works. I'm just saying Zach will not steer you wrong and its not impossible that a good port job or your stock head with plenty of n2o might be more money wiser spent..
Mine loves higher rpm so far pulls hard over 3500 to 4k(with minimal throttle) , but spool up has been pretty amazing as well. He did port mine to get a decent chunck of low end flow. I still havent gotten the balls to do a full pass, but did install the turbo blankets and intercooler today! A 75mm turbo should not spool this easy.
