Just wonder what you guys think. I ported my heads, just blended the bowls and smoothed things out,didn't open them up any. I changed the cam from a Crane 2031 to a 2040. Lost another 50Lbs out of the car. Put in new bearings and re-ringed the pistons. Indexed the spark plugs. Added Long tubes. Ran a 12.73 @ 107.45 last year.
