Inspect the pick up screen for rtv or gasket materials, or any other forgien objects. Buddy of mine found a wire nut in his.

Wish I had pulled it but wanted to keep everything simple.

I’m not saying they don’t have a different port design, but actual vortec heads lack the center two bolts on each side to the head where the edge passage is on them. But the big thing that is unique to the vortec for visual id is the vertical bolt location where the manifold bolts to the head. No other SBC head used the same style or pattern. Even the LT1 was different.Yeah, I don't know either but the ports are definitely vortec. Quite a sight to see the first time having only dealt with older heads and dirtbike engines. I know they got reworked some when the machine shop had the engine.
