Help with Head Gasket selection

The straight edge is straight. I checked it on one of my granite flats and use it on edge so it won't bend. I will verify with my scraped in parallel. it is so straight/flat that if you try to lift it straight up off the granite, it won't come because it is pulling a vacuum. If the deck is that bowed, I have bigger things to fix, so I hope it is the rods. Think I'll leave the crank in but pull the rods and pistons. I just need to know for peace of mind. I think I can check if the throws are even with the rods out too. I might as well, it only costs time.
