RPM Heads oil return hole
Just wondering if anyone has modified their Edelbrock RPM heads to increase the
size of the oil return hole? It seems to be much wider at the bottom than the top,
and smaller than on the stock heads. If anyone has done it what size drill did you
use? How long have you run the motor ( ie no issues ).
I fitted a high volume oil pump so I am thinking that the oil will take longer to
return to the sump, and there will possibly be more of it, hence the question.
