im running the gmpp cnc heads and valves. they have the hollow intakes also. i was concerned about it at first, but then i figured there are hundreds of thousands of these engines out there with hollow valves, and the amount of failures is very low. every failure i uncovered was on a cammed car though. i only found failures due to broken springs on the new camaros. the popped valves i found were on caddy's and corvettes.
