Steam vents

Before I get too far along in putting my engine back in, I have a question about steam vents.

Question I have is: two or four? My LM7 truck engine came with just the front two. Rears are plugged? Seems like having all four plumbed would only be a good idea.

Thoughts?

You only need the front 2, that’s why the factory only used the fronts on the later engines. But be sure to bleed the system properly and thoroughly.
