Highest flowing sbm heads?

How handy are you? If the engine was free, you wouldn't drop a nickel to the dollar on building a "W" headed stroker in a race block. Somebody should put together a "fair market" "W" headed stroker race block" cost, and make sure it has street manners.
What's street manners? LOL...if I want dead smooth idle and acceleration I drive my Toyota...I think your missing the point as to why most have no interest in modern hot rods
