closed deck



pros: increased stability at high rpm's
cons: may cause cooling issues

open deck



pros: better cooling than closed deck
cons: sleeves can move and shift at high rpm's unless braced

the differences are pretty obvious

Not only high rpm's, but under high boost levels and cylinder pressures as well.
