| RE: 390 2V heads....to modify or not? |

If you're not looking for higher rpm, then there's not a whole lot of bang for the buck in modifying or replacing the stock heads. FE heads flow exceptionally well compared to other Ford or non-Ford heads so the urgency to port, blend bowls, multi-angle valve and such just doesn't have as much of a payoff.
You're under the assumption that there is some difference in 2V and 4V heads. There isn't. There are different head types, like Cobra Jet, medium risers, low risers, tunnel ports and such but none of these are necessary for your described needs. An example: The heads on a 67 Galaxy wagon with a 390 2bbl are substantially the same as on a Shelby GT500. So just about any FE truck or passenger car heads you find laying around will do fine. Put the money into a good valve job with guides and seals.
If you're not interested in performance over 5k rpm, then look at the Edelbrock Performer (not Performer RPM) or if you're not weight conscious even a factory iron 4V intake.
Call a cam company and get their advice for what would be an appropriate cam for you. They'll ask a lot of questions about how you drive the car, transmission type, gear ratio, vehicle weight and such so be prepared. |
