For what you have I'd call summit and just order one of there rebuild kits. Assuming you'll have the block squared and the heads done. I'd use the piston the gets you as close to 9:1 as possible. You could mill the heads .030 and use the steel shim gasket and you should have decent compression. As for rods, tons of choices out there for a decent price. Even a stock LY would work fine. I had a similar build and used the summit 488 cam and it worked very well. You might want to call a "cam guy" and have one cut for your application. FWIW my maybe 9:1 unported 906 headed 67 440 coronet went 12.90 @ 104.
