How to pick LS6 & LS2 heads difference
Is there anyway to tell them apart at all. Obviously without pulling them apart and weighing the valves???
Are valves magnetic in one or the other??
Being LS6 are hollow stem and ls2 aren't??
The only way to know would be to weigh the valves. LS6 head casting number is 243 which is the same as a 799 and both of these can be found on Gen IV LS 5.3 engines.
