Glad you stopped by! They are gun drilled and cross drilled. We hit 3 sides of the exhaust port, pull water past the seats and spark plug area, and any other critical areas specific to the head design. I know it seems like a small amount of water compared to conventional "jackets" but we have lots of heads out there running setups similar to this, so we are very confident in this design. We actually have plans to do a set of 5.300" billets for a twin turbo drag week car, and this water setup will be used. We're confident.
