Small block Mopar ProMaxx head testing

What about those funny lines in the intake ports....?
Casting impurities prone to crack later on or nothing to be concerned about?


Most heads come with those casting marks and are usually removed by porting work. I personally would never run a set stock because I do my own porting but these heads are very nice. Here are some pictures of the set of Edelbrock heads I bought last year. I already started porting on this set and they have the valve job opened for a 2.08 intake valve. Edelbrocks lack of quality has gone down-hill.
