anyone know how much the exhaust port has been raised on this head?

3/4" I believe. Same as the SR.

Not just raised, but spread out wider than OEM, too.

mopar dave...if you're thinking of header fitment, typically, a low deck w/ raised port heads will use an RB header. An RB will need specific raised port headers, or in some cases, a standard fenderwell will still work w/ the raised ports.

The 440-1 exhaust ports are way bigger stock, width and hiegth than any other head, except B1, B1MC, made out there that I'm aware of I had to have a special set of headers made to clear those ports TTI makes and sells them, I'm a dealer for them also

The ports are larger than std. ports, but I've seen people using standard headers w/ Indy heads. Not the way I'd do it, but I guess it works OK. Obviously there's some restriction there. You can take a normal set of headers and have the larger flanges welded on...may save some money over a set specifically for those heads. Especially if you already own a set of std. port headers. Personally, I've always used the TTI headers made for the larger ports.

We went from a RB 440 block with eddy heads to a B 400 Indy Max block with 440-1 heads and used the same set of headers. What we lost in deck height with the low deck B block we gained in port height with the 440-1 head.
The ports in our headers were already very large so that was not an issue for us. Yes the 440-1 has a very large exhaust port window.

Ok. Thanks for clearing that up guys.
