RPM differences between LS6 valvetrain vs LS2 I notice the LS2(budget 243) castings out now and comparing those with true LS6 heads with the lighter valves.
1. Would LS6 heads have a higher RPM ceiling than LS2s?
2. Would LS6 heads rev quicker than LS2s?
3. Do the lighter valves of an LS6 head allow for using springs with less open/closed pressure than if using LS2 valves? Cam lift being equal. Well thinking of a TR OMC or similar custom.
4. Would titanium retainers in the LS2 sufficiently reduce valvetrain weight so that the the LS2 responses to Questions 1,2,3 would be different?
Thanks.
