OK, your stack is 9.015". Now you need to know the block deck height so you can determine the head gasket to use in order to put your squish/quench at 0.030" to 0.032". If you can't find a readily available gasket, you'll need to cut the decks to +0.004" and use this gasket.....

Or cut them to -0.009" and use the Fel-Pro 1003. This is based on a static compression ratio of 10.5:1 to 12.0:1, which is what the cam will want.
With the piston at 0.004" down in the bore with the piston at top dead center and using the gasket shown above, your static compression ratio would be 10.68:1 and the squish/quench would be 0.032".

The cam you have chosen will want to cruise at somewhere between 3800 and 4600 rpm's. Sort of makes your 700R4 choice look a little silly, doesn't it?????

That cam will also want somewhere between 10.5:1 and 12.0:1 static compression ratio to work right. Good luck trying to run the motor on pump gas. The aluminum heads will help make it work, but you'll need a really tight squish/quench. I'd be engineering it down around 0.030" to 0.032" as I suggested above.
