Building the ultimate turbo LSX---head Q's I can't get any real answers in the advanced section so I'm posting here as well since it's an FI motor...
I'm in the process of building the ultimate LSX engine. It will be an LSX block with dry sump, Callies Magnum 4" stroke crank, 427-434 cubes, GRP aluminum rods, custom solid roller turbo cam, Jesel belt drive, etc. It's going to have two GT47-88's for boost and water to air I/C.
My question is: Do I go with ETP's biggest 6-bolt head? Warhawk's biggest? or the LSW 12deg Hurricane's from All-Pro?
They've got to have 6 bolts per cyl for this application. I'm looking to make 2000+HP
And yes, it's going in the Supra!

I am in the process of your exact build except I have a single 101mm turbo. The ETP canted valve 6-bolt heads were mine and my engine builder's choice. Who is doing this build for you? I would highly consider discussing any engine components with your engine builder first. Most builders would prefer to pick their own components based on their experience to properly meet your performance requirements.

I have pictures of the LSW heads. They are going in my 427 build. From what Richard at WCCH says its one of the best heads for a LS platform. This coming from a guy who see a lot of different set ups.

Yes, the LSW heads are top of my list. They are 6-bolt design.
The Supra actually has a huge engine bay, and would easily accommodate a turbo big block. You'd be very surprised. I've got build-up bids from LME, and am awaiting bids from Pro-Line and another shop.

They are my favorite aftermarket castings as well, so I am not dissing your choice, I just wanted to point out that Richard has a vested interest in selling those heads. If I was him I would say the same thing

I plan on spending $5k or more for heads, the ETP 265cc are around $4800 with just springs and valves, add in Jesel shaft rockers and you're around $6500. I haven't talked to AllPro on prices yet, but Pro-line recommends the Warhawks. I'm waiting on their bid, and then I'm going to quiz Steve Petty on all this.
