4V & 2V heads/manifolds

Right you are, Phil

The grocery getters with the Cleveland got a two barrel carb, and smaller port/valve heads than the performance four barrel carb engines. There are other variations between different varieties of the four and two barrel heads, but someone else will have to get into that story.

4-V heads had gigantic valves and ports while the "little" 2-V heads only(?) had valves bigger than the largest ever supplied on 350 Chevys. 4-V valves & ports directly compare to those on the Ford 429/460 engines, prompting some to describe Clevelands as 'small-displacement big-blocks'. In the lower corner of each head is a cast "4" or a "2" designating the head type. 'Course if its off the engine, try shoving your hand inside the intake port- most hands can go in far enough to touch the 4-V's intake valve!
