Go with a set of 55-60lb 'ers to support your fuel flow needs and only a dyno tune will tell you what fuel pressure it will need to be run at. I would suspect to start with though....40-42lbs is what you're going to start with.

Siemens-Deka 60#'s would suffice
but 42's would be cool as well

I'd do 60's. 42's won't be enough.

Siemens-Deka are really the only brand I know of, personally, that has worked well for others. And the type of injectors have nothing to do regarding if you have a stroker or not. Cometic head gaskets might be a good idea from Livernois Motorsports. Go to the dyno/track for the rest of your answers.
