12mm

Hey guys! That's right, after a longer than expected wait, these are back in stock and ready to ship here at Lethal Performance! Compatible For both Gen 1 & Gen 3 Coyote 5.0L as well as the new 5.2 Predator from the new GT500. NOTE: This kit is for 2011-2017 blocks with deep head bolt...

Seriously considering getting a gen3 coyote short block, but would be using my gen2 heads. I know the head-bolts are different (11mm vs 12mm). I've heard I can just pickup any gen3 head stud kit and put my gen2 heads right on, is that true, and is it just any generic headbolt kit for a gen3...
