On the Cleveland crate motor; the desc says 3V heads which would have to be the CHI heads i mentioned earlier. But they spec the Edelbrock intake, which surprises me since CHI makes an intake to match the heads. My CHI 2V heads required an Edelbrock as CHI doesnt make an intake to match. The 3V was just out when i was building my mill so i didnt buy them. Mistake. Also they spec a stroker crank, which is fine but that could require some custom block work and also experience with spec-ing the right pistons, which is not a real big deal as long as you are working with a shop that has built a LOT of Clevelands...which wouls again suggest working with DCE wince they are so close. Also Richie is a genius at setting up stroke/compression ratio/cams for usable curves. Also they can dyno the engine for you before you take it out the door...and Jeff next door can chassis dyno the carb, ignition, and tranni after you drop it in. Saves tons of time.
