[I think I have reached the conclusion that porting and polishing the heads on my car is best way to get the performance I want without atracting the unwanted attention of the warrenty police at my dealer, I am hoping with my existing mods that this will keep me happy for a while ,any coments or advice would be great

The Dealer can tell the heads have been off the car. Unfortunately there is no 100% undetectable engine mod.

We are lucky to have several mod friendly dealers here in Texas. I have had no charge warranty work performed on my Lingenfelter motor:surprised
