Roy, I would go with the Stealths. One of the magazines tested a pretty average 440 back to back with 906 heads and the Edelbrocks, which flow in the range of the Stealths, probably just a little more. Anyway, it was a 440, 9:1, Comp XE268 (which is similar to your cam, just a tighter lobe seperation with 112 degrees and its 224/230 duration. Eddy RPM intake and 1 7/8 headers. They dynoed 399 with the 906 heads, and 473 ft lbs of torque. With the Eddies it was 456 horsepower and 514 ft lbs of torque. Peak torque was at the same RPM and peak horsepower went up only 200 rpm.
I think even a stock HP engine would benefit 20-30 horse from Eddies or Stealths.
