Question High compression heads and Spark Plugs
Hi Folks
I have a 02 SS M6 - I am replacing my stock heads with GM's performance LS6 Cam & heads, the heads are ported and shaved - giving me a Compression ratio of 11.7:1. What plugs should I get and gap should they be set to? I don't believe the stock gap will work 100% with that compression ratio.
Thanks
Bill
