I have original iron high riser heads and at one point was considering if alloy E-Brock heads were available that would fit my high riser 2X4 intake. Couldn't find anything, but then again, maybe I was just to 'lazy' to look hard enough.
High Riser heads do not have the exhaust crossover typical of the other FE heads, not to mention MONSTER intake ports. It was tough finding gaskets for the intake!
Which fits ONLY High Riser heads...
