Sorry,
A little busy, and didn't get back to see your post, ..
T&D has a shaft system with a one piece intake stand, .. about $1400
Jesel has a Sportsman system with individual stands and a tie bar, $1150
Depending on who's CnC head you use would effect the piston, but as
of right now a dome to fit the stock un-ported chamber and the Musi CnC head
is available from Diamond.
A custom piston has been designed for my chamber by Diamond and available
through my shop but my chamber will also take most aftermarket dome shapes, ..
but like with any race part, you need to check and adjust.
I also have a "small" CnC chamber kinda like the Musi chamber but it sacrifices
flow numbers all the way through the lift range.
I have the stud girdles in stock, . . ..
Current TRUE flow numbers

.1 - 74
.2 - 160

.4 - 313

.6 - 403
.7 - 432
.8 - 448
.9 - 455
