Just recently I read a response from Paul Kane to someone on this topic. I'll see if I can dig it up.just curious, does anyone know how much one could mill off the deck of a BBF block? Could you take it down to even 10.2 or 10.1?

Generally, the purpose for cutting the deck is to shorten pushrods, shorten intake runners and have a reasonable rod length with really short strokes but IMO, other than rod length, you have to cut a lot more off the deck to make a real difference, like under 9" for real short stroke Pro Stock stuff.Paul's post....
"I have found the most of the cylinder decks in these engines to be 0.420" thick before being cut, except for one area that is 0.375" or so. Hell, you can cut them down to 10.200" if you want.

Another post.....
"I've gone as low as 10.125" but, you'll mill into the upper belhousing bolt holes.
10.200" is actually pretty common with lower cubic inch "class" engines."
You missed one of the most important parts is to help stand the head up.Generally, the purpose for cutting the deck is to shorten pushrods, shorten intake runners and have a reasonable rod length with really short strokes but IMO, other than rod length, you have to cut a lot more off the deck to make a real difference, like under 9" for real short stroke Pro Stock stuff.
