Edelbrock rpm head question

Hello-great forum!!
I have a set of Indy/Eddys-The 1st thing I noticed was the oil "returns" were way too narrow and not cast far enough towards the ex side of the heads.
I found this out when I pulled the v/c to set the lash-my springs,seals guides were bathed in oil-what a mess.
So i spent 3 hours making it right-with the heads off of course!!!
