No Im saying is start out right. Hell yes beef up the internals. But why the heck would you use the 2.5 heads unless you wanted the bump in CR?
Remeber the 3L heads flow better. Use the 3L heads and then upgrade your rods and pistons. But don't start with poor flowing heads and high CR and expect to just throw some forged rods in there and everything will be ok....
