All those fancy parts and no mention of dry sump oiling or fuel injection?
Why go halfway?

(kidding)

Agree with you.

Why not finish the heads and intake manifold with Tim, pay him, get them in your hands, and
then do the rest of the project under the guidance of someone who doesn't assume you have an unlimited budget?

Maybe even someone more local, where you can get involved more, go visit your project in person and talk face to face.

Just a thought......

Personally: The minute someone refers to parts I'm going to provide as "Junk", my reaction is usually:
"I would never ask you to work with Junk" and that is the end of that transaction.
