340 X Head Valve Options

I was actually thinking hardened seats on both, just to be safe. So yeah a 2.05 would still fit I would think. I am just really curious if this 30 degree face angle can be done. Supposedly its better than the 45 degree angle at low lift, which I am thinking about topping this thing off with the Eddy Air Gap and want the broadest average torque curve I can get and still build a valve train that can handle 7k rpms.

I have seen some 2.05 nail head valves but none of them are the stock mopar length... a stock chevy is too short, the plus .100 is too long. Would that throw off my rocker geometry? How easy is it to cut the stem to length?

Thanks wild&crazyguy, I was hoping you would chime in on this...
