what I did was give the machinest a one piece intake gasket as a template, so it will clear the nuts, and then I'm having him flatface and dril out the injector ports on a 30° angle to it points right into the intake port

 

Hi Cal,
That is a good start.
Then the fun begins.
You might want them to machine the flanges for the exhaust too while they're at it, as it might be cheaper for you.
I'd still recommend doing them individually having done this before.
It's in a confining area and doing one at a time and then joining them together at the collector is the best way.
But, if you do want the flanges for the exhaust I need to know asap so I can let them know how many to make.

 

Just an update here:
I have the intake components in the works at the machine shop and hopefully next week I'll have them in my hands, along with the exhaust flanges.
The the real fun begins!

 

OK, At long last,
I have one of the parts for the Jag intakes.
We had to rework the drawings a few times to get them really right but I'm extremely happy with the design.
I'll be posting some pics of them soon.
The first set will be on the test engine going in the '36 Chevy pickup, and the second is going on the XJ-13 engine I'm building for Scott Pinsky's car, which is really coming along very well by the pics I've seen.
