And spend 2-3 times as much $$$$. No one has asked what he wants to do. All he asked was if they were interchangeable, not what YOU would run or prefer, but if they could be swapped out. |
They can be swapped out, plane and simple. You would need additional machining cost's to the 6.1 heads to keep your compression ratio under 11:1 if you plan to put the 6.1 heads on a 5.7.

Is there a way to put a set of these on my LS1? :drive: The new heads I'm looking at are the L92 which will flow 375 or more CFM with little work. If you want big heads for an LS1 thats what I would get. Thomas |
