Default Heads for 415 LS3

I'm building an LS3, stock bore/4" stroke. I plan to be in the 14:1 compression range.... I'm going to run a victor jr with a 4150 TB. It's going in a 00' z28 w/th400 and it's a 1/4 mile car. I don't care about street manners.

I've been looking at running cnc'd L92's. Specifically TEA's, my other engine has TEA 243's and I was satisfied with those.

These are the last big decision to make and I want to make sure I'm making a good one

What do you guys think?

With that manifold the heads are only part of it. A better manifold and bigger tb are a must to make power

you don't feel that a Victor jr and a 4150 TB will be enough?

Mast claims their manifold and a 4500 is worth 50hp over a jr and 4150.

If the manifold is not up to the task the heads wont show what they can do.
