To the OP:
You are out of line.
1. Brzezinski does not do Extrude Hone, they get inside the cast iron things and work on them because the racers they service are limited to cast iron. Some they cut holes in or cut them in half to allow access. I suggested them because they are experts in making stock cast iron stuff work and because the times I have called them to ask a question about something they have been helpful and courteous.
2. Check my post, I did not use the words "Extrude Hone".
3. In your original post you said you wanted it "to look stock". You did not say you HAD to use the cast iron intake. I did read your post more than once.

Enough time wasted,
R.
