also, i wouldnt think that geting a 408 over the 400hp mark would be to difficult with either head as long as the set up is right

Yea,but its not the best way.....

You can either #1,stuff some rags in there and use a die grinder and a light touch,or #2 you can get a fly cutter that mounts in the head (witch of course means you got to take a couple valves out).

Isky makes the valve cutting tool,and of course you can take it to a mahcine shop and they MAY be able to do it.

Cometic can be stacked (you add in an extra inner layer) to what ever hieght you need.

And you can also get coppers in pretty thick.

Only you got to watch you dont ruin your quench area,that will cause some detonation.

I'd be more worried about the radial clearance then the deep dish. Nice chatting with you

i know it pretty pathetic but i guess this is where guys tell you it isn't what the number on the dyno that matters its the number on the time slip and how the car feels.
