Having raced Cleveland I would use the stock crank and rods depending how fast you want to go. I have turned the stock crank and rods to 7000 with consistent success. Just get your crank shot peened and you rods put ARP rod bolt and get them stress relieved and use ARP bolt every where. If you are going to put it on the street stay with the 2-v heads. In my current Cleveland street car I am running 12.9's and I have about a grand in the motor mainly from using the stock parts (most stock Cleveland parts are pretty stout) where I could since I am not spraying it I ran hypertecnic pistons. Just remember Cleveland love the rev's so don't be afraid to rev it.
