Bigger stock type end castings

[S/P4884]

 I was in the junk yard the other day and found a set of end castings that were bigger inside than a stock casting. There are no markings at all on the castings. There about a stock size port on the head end but there cast bigger and could be ported out. Looking in the manifold end they are definately bigger than stock. I assume they are no longer made but does anybody know who made them?  When I get them cleaned up I can post a pic. The only other performance part on the motor was a blue coil... weird!!

I may be talking out my butt, but I was looking into such an endcasting for a turbo set up, and was told that Bugpack made "Trick Flow" endcastings quite a while back.  I'm no expert on this subject, but thats what I remember... after 3 days of damn near 20 hr work days! 

I know a summer or 2 ago, I was looking at the CB booth at Fontana and they had a prototype bigger endcasting on the table.  I was drooling over it!  I don't know if it ever made it into production.

I seem to recall that a company called Station One made them and also Bugpack.

I have a few sets of the Bugpacks.
