Need to drop CR
Pretty sure I need to drop my CR. I'ms till at 10.1 with stock LS1 ported heads. I considered the 317's but I was told they only flowed 5cfm better than a stock ls1 head. I wasnted something I could benefit from a lower compression and just an overall better flowing head. I will aslo be running anywhere from 10-15 psi. Thanks in advance.

well a stock ls1 head flows like 227cfm at 600
the stock 317s flow 24x at 600
the 317s would drop you down closer to 9,10cr
I have a set thats been hand ported bare casyings i might sell cheap
