I have the 60105 Voodoo cam going in my 406. The heads I am looking at are Bodix IK 200's with Comp Cam Springs. So far, Lunati has not been overly helpful, so I thought I would try you. Below is a chart for the spring that Lunati recommends for the cam and the Comp Cams springs that come with the heads. Do you think I will have any issues?

Lunati 73943
OD - 1.266
ID Outer - .833
ID Inner – NA Single
Seat Load – 110 @ 1.750
Open Load – 345 @ 1.230
Coil Bind – 1.160

Comp Cams 987
OD - 1.430
ID Outer - 1.070
ID Inner – .697
Seat Load – 121 @ 1.80
Open Load – 343 @ 1.200
Coil Bind – 1.150

Just break the cam in with the outer springs only, and after you change oil and filter, put the inner springs back in. This assumes the Comps have 2 springs and a dampener.
This is the same advice I give for the Lunati spring also......
