Here are a few charts for a .030 over 10:1 short block with stock E7 casting heads and roller cams. I looked up the Comp 266HR, B303, E303, Stage 1 Trick Flow, and Comp XE270HR. All should have a little bump to the idle with the exception of the 266HR, but should work with a stock converter.
I like the torque curve of both the B303 and the E303. The XE270 made more horsepower, but looks like it may be lacking below 2k rpm.
