Spraying carb cleaner on there is also a good way to clean one.  I soaked mine in lacquer thinner for a few days then hit it with 120psi air gun. Theeeeeen OCD'd the spray holes with  4 penny finish nail.  You should also go with a high flow oil pump from a turbo ZX if you really want to soak the valve train. 

the final test is to "briefly" start the car with the valve cover off, it will sling oil everywhere so take nessasary precaution. "nuke it from obit its the only way to know for sure"

Nuke it from obit?

That's funny Kim Jong.

My bad!  I didn't catch that, I was watching Fast Times and The Breakfast Club...

 

I say we take off and nuke the entire site from orbit.

It's the only way to be sure.

I beat you finally CO!

Haha!!!

That movie had a lot of good lines, esp from the late Bill Paxton.

oh back to the orig comment, run it without the valve cover to check function of the spray bar very long and you will think something was nuked from orbit from the mess it makes.

My laser cutter makes gasket making super quick and easy.  File attached if someone needs it.

I've decided to fit the newer version of the spray bar.
