Small Block Head Flow Chart - Discussion.

Unless you do the same uniform hog out, short turn shape...depending on the goal can be different for different heads.

Lamens... the wrong shape can kill one end or the other, high/low flow.
You can get the lot together IF you can widen it enough right before the turn and run an even lip across the top. It's all about the shortest path, one will suck the other down with it

.and then you only have half a port working.
It's not easy, it's sometimes not hard... its science.
