Also check the price/dimentions of speed pro 1166 and H405cp pistons. I assumed you were going to rebuild the OE open chambered heads. If going aftermarket I'd for sure step up to magnums (closed chambers) & get .040" quench. It'd let you run a higher CR on the exact same octane & have an maximum efficient long block w nothing left on the table
