I got my heads converted from single to double valve springs.

Now I am putting the 9550 Cam setup in my engine and was wondering if I can just convert them over to the HD Valve Springs that come with the Kit or not?

Len Hoffman said I should use "Crowler Springs" I never heard of them and was wondering if anybody can tell me something about them?

Or are there any other solutions?

Not knowing what springs that were recommended, we used Chevy dual springs on the race car.

We also had a spring tester so we could determine the length of the installed spring for the seat pressure and over the nose pressure we wanted (valve train control).

Further, we would polish the ends of the spring and run washers underneath to avoid the sharp edges of the spring cutting into the head.

Lastly, I hope you have the figures for installed height and avoidance of coil bind on compression of the spring.

A lot more to it than just running "dual springs".
