Hello, this is my first post on here. I'm researching to prepare for my first build. I am up in the air on making a decision between the Promaxx and Edelbrock heads for my 318. Have the Promaxx heads still shown to be reliable since the last post on this thread? Thanks!!!
I only know a couple of guys that bought and used them. The set I checked out are being used but not raced.
