Thinking about LS6 heads and TR220 in my 5.3.
As the title states, any suggestions. I'm pretty sure I need to mill the heads, but I don't know how much looking for a 10:1 cr. has anyone ran this same setup, if so what gains did you see. Also considering punching the block out to 5.7. Any feedback is good feedback.

My WCCH 5.3 heads are done but I'm going on vacation so I cant' get them on for a couple of weeks. They are ported and milled .030. Richard said this would yield around 10-10.25 CR.
