High compression with aluminum heads and pump gas???????

There really isn't much of a choice for gaskets... Run the Felpro 1008s.
Static ratio isn't such a big deal as long as you chose the right piston in order to have a tight piston to head clearance to create quench (if it was me I'd be setting it at .030 by decking the block to bring the piston proud of the deck) and the static ratio you want. Run a cam suited to the combination and your fuel type.
