IMO, your build is at the next level up from mine. The Art Morrison chassis and twin turbos goes well beyond what I have done.Love this build. I have a 70 fastback that ive owned since 97 and I'm slowly getting back at it and this build is right up my alley. My car has an art Morrison chassis under but most of the rest is close. I'm planning on twin turbo coyote and a t56 magnum. I have everything and unfortunately my chasis was buikt before coyote engines were built so we are fabbing up mounts now. The one piece I need is the booster setup. Your hydratech looks great, called today and they are no longer taking orders cause they are so far behind. That wedge may be the way to go. Tried to find him on ebay but no luck. Those headers turn out good for you? Jimmy is a good friend and they do great work. Looking forward to following this build and bouncing some of my car off of you
I bought a wedge, then went with the Hydratech HB system and sold the wedge.
I think Ultimate Headers did a good job. The only annoyance will be the installation. Only about half of the header bolts will be accessible straight on, so a lot of work with a wrench from the side. Not ideal, but I am sure the installation will go fine. I will install the headers on the engine outside of the car making their install much easier. Since I was one of the test subjects in working out the latest design, I did not have them coated. I wish I had coated them by UH when they were there. The locals want a fortune to ceramic coat these headers.
For the HB wedge, here is the contact info I used. Email him and see if he is still making them, just ask to mill it for the 2003 Ford HB. I bought mine in 2018 and it was $287 then, hate to think was it will cost now.
