Trick Flow 440 heads, The Real Deal?

I have a silly question.

how are the valve cover bolts drilled? on my eddy heads they are not drilled 90* to the gasket surface. they are drilled at an angle like the factory iron heads were. I cannot use the fancy fabricated valve cover with the eddy heads because the bolts are not straight.

The Edelbrock heads I have here, RPM and Victor, have the bolts holes drilled and taped perpendicular (90 degrees) to the valve cover surface, just like the TrickFlow heads. Looks like you got some weird RPM heads there.
