Lets get this terminology right. A camshaft with a later intake closing event does not "bleed off" anything. Bleeding off gives the impression that too much compression is built and the camshaft somehow magically makes it disappear. Ain't how it works.
Closing the intake valve later in the compression stroke means that the cylinders begin to build compression later in the compression stoke. That means the compression stroke is shorter than a camshaft with an earlier intake closing event. In short, you cannot "bleed off" compression that is not there. That is just incorrect.
All that said, IMO, if deck height is zero or close, then the OP will probably be ok, because he will have the aluminum heads AND some quench on his side. True that a domed piston is not the best for quench, but he WILL still have that effect. I think it's worth a shot.
