Default Speed Inc Si7 cam with .030" milled LS6 heads, need to flycut?

I picked up a Speed Inc Si7 cam, I currently have OEM Z06 243's (sodium valved) milled .030, using the GM MLS .51 thick (compressed) head gaskets. How much (if any) should I flycut for these?

Thanks!

Well thats easy, your going to have to measure it. Its the only way. Could call speed inc up but probly would tell you the same. Measure.

I've heard about a couple different methods, which do you recommend? One involves a light valve spring, the other I've heard was done with clay but I couldn't really understand exactly how the clay was to be used...
