What would these do on my 6.0? It's a lq4 what compression would i be at

 

Man I'm not the guy to answer that, it should raise it.

 

Probably in the neighborhood of 11.3:1 compression ratio on a LQ4

 

x2 . iam on a lq4 with 59cc ia, at about 11.1:1 with stock head gaskets

 

Are they angled or flat milled??? How much where the heads milled total to achieve a 58cc chamber?? Any flow numbers on hand....???
