Turbo LS Steam Vent question

[MPac]

Alright guys quick generalized question, I'm building a turbo LS right and when I got my heads back the blocks were gone for the rear steam vent holes, I'm doing the AN style set up on the vents and was trying to figure out if I should get blocks for the rear and just run the front steam vents or run a 4 port set up on the steam vents? What's the pros and cons of each route and which would be generally a bet setup to go with, I would think the 4 port style would be better. All I know is this is the first messing with an LS and wanna get it right.

Bump.
I'd be interested to know this too. I've always just run the factory set up, but that doesn't mean it can't be improved.

Based on this article and your application, I think you should run all four vents and route them directly to a proper surge tank. You will need to read the article.
