Pump gas combo that had a heads swap from stock E heads with minor port work to stock KRE high ports, close to the same compression, same cam. The car ran the same ET and MPH after the head swap, 11 flat. A couple cam changes and still ran the same times. Eventually the heads were milled and retarded the cam timing to get down to the mid to upper 10s.
