Trick Flow 440 heads, The Real Deal?

I would probably use the Comp Cam 938 spring, set up 200# @ 1.900" installed height, 490# @ 1.300", w/ coil bind @ 1.225, and use a tool steel retainer.

Good information and advice that I will heed.

One last question. What about using Beehive springs with this cam?
