A Fel Pro or Cometic should be more than what is needed!!! I am talking MLS. I noticed Summit is selling a MLS that is their normal friggin head gasket.
6% over is nothing on a street motor.
If it is steel multilayered it is the one. The bottom price new will be $80.00 each.
I am going to contact Summit tomorrow and have them fix their total crap. |

i agree with Adam. ill be using Cometics on mine (nitrous motor). i would check the gasket surfaces on the head and block. 6% shouldnt blow a decent set of gaskets.
