Questions about a 2006 5.7

They bolt on but the compression ratio when combined with the pre-eagle pistons is pretty high. There are fixes, and might work for some as is too. Just pointing it out.
Thanks for the info. I use this combo in a racing application at 13.5:1 compression ratio. someone who wants to run pump gas would not be interested in that. I know they make very thick head gaskets, maybe for this reason.
