I agree with you, but just wondering equal length compared to non equal length given the fact we do not crank these engines very high.On an NA engine long tube will yield more power. There are many threads on this topic.
I agree and have used both on builds in the past but these are engines with 12.5:1 compression and above and turned 8500+ rpm, different animal.In principle equal length provide better scavenging but it looks like you want actual dyno chart comparisons. IMO just going to LT headers puts you ahead of the game.
