The small exhaust valve is the least of the worries. The above cam being a split duration will help address this.
Go for the ignition upgrade and windage tray.

Anybody know the stock comp. ratio of this engine and possible stall converter ratings?

I agree...but if those heads don't have hardened seats....it would be good to do the bigger exhaust valves while doin the seats, wouldn't it?
