The EQ heads also have 58cc chambers vs the stock 61-64cc deals, so you can add a little compression there as well, and they make a good clip more power. I would highly recommend getting the EQ heads with the LA style intake pattern, as it really opens up the intakes you can run, including the LA style RPM intake, which is hands down superior to the Pro Products deal.

Do they typically CC out to 58?
Everywhere I read they are 62-64cc, even the individual at AAmidwest,when I called approx. a month ago,said they CC to 64 typically?

"The heads are cast in Australia, using a technique that produces an exceptionally smooth port surface for more flow and power, with 172cc intake runners and 62cc combustion chambers."
