If you're going with a stroker, then in my IMO I would use a set TA aluminum heads with a 4 bolt header. The idea of a stroker is more cubes. The more cubes the more MAF. The more MAF the more/higher potential hp. Don't want your heads to be the bottle neck. Some people might say they're not necessary with a 6262 turbo, but what if you decide to use a bigger turbo in the future? Time to spend more $$$ to do it over again.... Now, there's far, far more experienced people on here with huge, vast amounts of knowledge then me. I'm just speaking from my personal experiences. And from the sounds of it you're not exactly sure either. So keep your options open when it comes to your build and different turbos you want to use in the future. Do it right once! Good luck.
