What does " open deck " and " closed deck " mean?

[deevergote]

Closed deck.



Open deck.

[Tippey764]

Closed deck.



Open deck.

I take it we are talking about the openings around each cylinder?

[deevergote]

Yessir. The open deck design is great for cooling, but not as strong. That's where people often get a "block guard"... which is essentially a piece that fits into that opening (usually just at the top)... block guards suck.

Most open-deck engines are converted to closed deck when they're resleeved and built for high horsepower applications.
