What exhaust manifold will you use with those heads? The stock LS3/L99 won't fit IIRC.

Modified zl1 manifolds. They required some welding.

Cool! I know it required some modification, but I wondered how bad. I guess the extra bolts on the heads slightly in the way or something like that.

The manifolds need clearanced and rewelded to clear the extra bolts. I have a set I was using before I went with ARH shorties.

No reason to run anything different.

What made you change to the shorties? Did they become a power restriction at a certain HP level? Got any pics?

I am moving over to a LSX sometime soon hopefully and trying to make sure I cover all these details that could hold up my build. Thanks.

Sorry for the thread hijack!

Kevin@AGP said the manifolds can be a restriction over 1100hp. I found a deal on a set of used ARHs and had them jet hot coated.

Basically, I had a little money to burn and spent them on the shorties. Manifolds have made well over 1000 hp and I thought I read somewhere someone on ls1tech made 1500hp with stock manifolds.

I can take some pics of the manifolds.

Working around the shorties is kind of a pain whereas the manifolds were tucked closer to the block and made it easier to do things like spark plugs, etc.

Gotcha! TIA for the pics. Looking to clean out your garage of some modded stock manifolds? LOL!

Mine made 1114HP at 20 pounds of boost and this is through a non locking converter and TH400 all on stock manifolds.

LS7 intake manifold

I realized that after I posted based on the shape of the intake!

When are you up and running?

we have a couple more custom fabrication things that need to be done. but soon, we are getting close.
