Trick Flow 440 heads, The Real Deal?

Old Man Mopar said

Thank you! This is a street motor; are the titanium retainers ok for street duty?

This is also the strongest of the spring packages they offer. All of them are rated for more
lift than my camshaft has. Is the fact that the cam is a roller what requires these springs?

Yes, it is because of the opening and closing speed of the ramps. The question being, which of the Trick Flow heads was set up best for your cam, that head is. If I was setting the head up for your cam I would not choose those springs......they are the best choice of the three.

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. Yes, the titanium is okay for the street.
