Predator Hemi

on the 60363 Hemi, all of them have the same size valves, which are the big valves you want. On the 69730 engines, only some of them had the bigger valves, which were the ones with RTC heads. Unfortunately, no way to tell which head is on the 69730 engine unless you can either open the box before buying, or see thru one of the handle slots.
