What Mixed reviews have you heard? i have the Indy EZ heads on my pump gas 440. which head head to use is kind of hard to answer. what are plans for the car? what size engine? i bought the EZ becasue i was going to build a 512 stroker engine, but that ended up not happening. nothi9ng wrong with the RPM heads, i ran a best of 10.56 at 126 in a 3400 pound 65 plymouth B-body that had a 12.1.1 compression 440. the RPM heads were box stock.
the Indy EZ heads i got off of Dewayne( porter racing heads) he had to tuch up the Indy valve job and did a very mild bowl port on them. other than that they more or less box stock. I think he said they flow around 310 at 600 lift on his bench.my best pass with them on 93 pump gas so far is in my sig. I think i have close to 3000 in them. but i think if i was to do it again i would off got the new trick flow heads. but best of luck in what ever you decide to do. Mopar65
