I know this was a question for Marty...I just wanted to throw in something I have been doing for a while.
I cut the chamber hemispherical and then cut the piston to match the radius of the chamber. So it has the unobstructed flow of a hemi chamber...but with a really good quench area...which was missing before. I am happy with the results of this so far.

My motors are usually so large that I would not be able to get the compression where I want it that way. They are either flat top or dished.

The piston I use is a segmented flat top.

awesome, fair do's nice bit of kit, have the heads needed to have much done porting wise, or they flow well pretty much out of the box?

I am just in from the Winternationals. What a great day!

The 910 heads flow fairly well out of the box on the intake side but not the exhaust. These heads have quite a bit of work done on the intake and extensive work done on the exhaust side.

Ok - I load the pistons into the cylinders and then install them together.

Pistons and cylinders in and on -

Heads on and longblock together -

So now I start fabrication of the intake and exhaust.
The car layout dictates how I configure the system and where I can locate various parts such as the turbo, carb etc. I have my own "style" and every car is different, so if they cannot bring me the car, I have them take a BUNCH of pictures and measurements and send them to me.

I get my flanges from various places.
These intake flanges for the 910 heads come directly from Autocraft and are what I start with for my plenum intake manifolds.

I then use 45 degree mandrel bends and tack them in place to the flanges (header fab is also starting s seen in picture) -

The header fab also is done at the same time. Everything must fit together so it is critical that clearances etc are all taken into account.

Intake and exhaust fab progressing.
You can get a peek of how the plenums are made up in this pic -

Header finalized -
