Question What angle are the valves on the Mod motors?

What angle are the valves on the Mod motors?
what angle are the valves on the modular fords? I know small block chevys are 23*, and the NASCAR heads for chevys were 18* for a while, LS1 has 15* valves, I think old dodge smallblocks were 18*. Are the valves on the modualr fords 0*? are the valves parallel to the bore centerlines?

My Ford manual for the 2000 GT says valve "face" angle is 45.5*.

that means they are tilted toward the exhaust by 0.5 degrees. Basically, parallel with bore center, but not quite!

This assumes the 4.6 is a 90 degree v8 of course.
