Dwayne that set of heads you did for me are still on the same 498 short block running 10.2's in SoDak. I sold the car to a friend of mine noting that it was a "roller that runs".... it was tired and needed a new short block and the heads freshened. It ran a string of 9.93 passes at Famoso prior to the sale. He ran it for two years and sold it... it's still getting beat on the last I heard. That was the most docile engine I've ever had. Shift light set at 5600, trapped at 6200. Low rpm, easy on parts (most of them stock.... LY rods, factory main caps, stock welded stroker crank). Great running mill in a 3380 big car.
