thx for the info I have a kenne bell supercharger on and I am hoping the heads open it up more, i had them port to flow like 290. Might you know of any chromoly head gasket that might be good to use, I am going to need a pretty thick one compared to stock.

The LSx engines have 2 different length head bolts, the swap over year was around 2003. The newer bolts are shorter. If you get replacement bolts for your 2003 4.8 you will be fine. They are torque to yield and are throw away after each torquing in case you didn't know.
