My core is.
Chamber is a pretty easy thing to change in tooling,
I am not sure who is behind that head. Maybe a joint venture with a couple companies like PBM and Blueprint. Who knows,
Maybe dieselgeek will clue us in,
Lorax, normally I love your posts but I think your presumption that "all castings from overseas that aren't Australia are simply junk" is not quite accurate. I'm one of two Calibration Engineers here, but I do work in Engineering so I asked about the picture as that is not a head I recognize in my 12 months with BluePrint (most satisfying job I ever had, and we have an outstanding customer service record, just do a little googling to confirm). Here is the answer I received:
We used the head in your picture but it was not our design. Our engineers and QC staff have been to the manufacturer and felt, and still feel, it was a well run outfit. But, we don't like using engine parts designed by someone else, so we designed our own 23 degree head with interchangeable port molds to make different sized runners. In all that's not a bad head, just not one we designed.
Remember, we put a long warranty on these parts and engines, and we do a lot of testing to make sure they'll last that long. In *my* experience, it doesn't matter where a part is cast. I have EFI customers making 10+ hp/ci on overseas blocks and heads - do you have customers doing that on domestic parts? I know BluePrint have engineers on the ground wherever our parts are made (some here, some overseas), making sure the parts match our drawings and quality minimums before we take ownership of them.
The bottom line is, Quality is the responsibility of the guy selling you the part.
