head swap

I plan on putting a set of heads from a 2008 4.8 from a truck onto and older style lq4 6.0 block. Any fitment issues I should know about? A stock lq4 runs about 9.5 compression, would that change with these heads?

I ran the same #799/243 heads on my LQ9. It just like any other head swap.

If your at 9.4:1 now you should be right around 10:1 after the head swap.
