I am looking at swapping heads and increasing compression at the same time to go from 10.7 to 11.2 on my LS3. From a tuning standpoint is it correct that I should expect to have to reduce timing for the compression increase? And if so, do you have a general ball park of how much timing would likely need to be removed?

Seems like you made a similar move to what I am planning and curious what the tuning changes were.

Thanks

Had it retune yesterday, would have to ask if he added or reduced timing
