Assuming your stroker kit with the .030" over Bore gives you about 455 cid you will need a total of 98.2 CCs above the top of the piston to have the needed 10.5 compression that you want for a Aluminum headed street or street strip motor.
There are many ways to do this, but one way you should not do this is with a .093" head gasket!
The KRE heads can be had in a 85 CC chamber so you would only need a small 13 CC dish in your Pistons to have a 10.5 compression.
If I had your combo I would be looking into a KRE D port Aluminum head since its power band will be far more productive for you needs.
