E-street vs Promaxx vs 440 Source

I only ever had one set of ProMax heads in my hands and they were my buddy’s standard port small block heads. I was impressed by the quality of the work, including the valve job. You may have seen the post I made about them.

I remember that post. I also know a guy that put the Shockers on a stroked small block. Seems everyone that bought or inspected Promaxx likes the work. The E-streets aren't getting much love in the votes, but PHR gave a thumbs up to them. IF I was ordering today, promaxx would be the choice.
