So in searching for any part number I can find that may clue me in on whether my intake manifold was powder coated or is an actual LT4 piece, I came across the fuel rail P/N. It is 17096113 0116 knl 2. When Googled, that shows LT1 and LT4, so does anybody have any idea? Thank you!

Lt4 engine uses different cylinder heads and intake manifold than lt1. The are not interchangeable between the 2 types.

Here are the part & casting numbers I have gleaned from internet,

Lt4 head casting numbers 12556890 or 12363287 Lt4 head should have lt4 cast into it.
lt4 head part number 12555332

lt4 intake part numbers 12550630 or 12550631

Can't say if any of these numbers are correct. They are what's listed out there in net land.
