Pulled the motor today and shipped off the stock stealths to Modern cylinder head for one of their CNC jobs. Hoping to shave 8 tenths off my 12.80 from last year.

I figure I need 80 horse according to my old rule of thumb (10 horse per tenth) . The guys at modern says they see 70 horse improvements on a mild 440 for their CNC job. I will know for sure come april when my local drag strip opens. If nothing else it will be a good data point for people considering CNC'ing their heads. If the heads dont make it go 11.99, I can add a little more cam later.
i ordered a custom cam from straub technologies, should be here in a few weeks. Then I can get to the track this spring and finally tune the car and see what the cnc stealths do.
