Thinking about it you could try guy croft his books on performance engines go for something like £200 there so in demand so he must be doing something right

How can you develop a cylinder head without a flow bench, engine dyno?
So if you apply that rule neither Karl Norris or Cylinder Head Developments have either!
And how on earth do you think a hand ported head is preferable over a CNC cut one??? As long as the port shape is good the CNC is best every time as it can replicate that port shape precisly in every port with no variation time and time again.

The main problem i heard is Jim used to do everything with the heads the development the computer putting the head onto the CNC machine Jim took great care that everything was 200% spot on
If your 1 mm out when bolting the head into place the whole head will be done wrong

The CNC heads make a good base but I think most people still have them fettled after which is a good enough reason not to use them.
Nik Waples, Karl Norris, Neil Roper are a few I can think of who I would use.

I would imagine whoever does the cnc stuff there is capable of bolting things down in the right place

Use a probe like,should come with the cnc miller can programme it to measure the head every time you bolt/unbolt it
