all things staying the same as they are now with the cover bolt hole location, what oversize hole would be needed to interchange the covers ?
or am i missing something on the prints ?
please understand i have never had any of these covers in my hand to personally inspect.
as always, T.I.A. !
I dont think its diameter of the holes.. I think its the angle of them
i "thought" [same as ASSume
] that the aftermarket heads and valvecovers were machined to have the bolt holes at 90 degrees to the sealing surface, except the 440 stealth head, which mimicked the stock bolt hole angle.
learning new stuff is fun for me.
that is, if i can just remember when needed !
with that said, what is the "most common" hole angle, or are they ALL different ?
