EQ heads, who's using them?
MAGNUM HEADS
We have been doing flow testing on our new Heavy Duty Magnum Heads, P/N 4666, and at this point, all we can say is sweeeet!!! These suckers can get lots of flow very quickly into the lift cycle. They have excellent flow characteristics for small hydraulic and solid flat tappet cams and especially good flow for use with hydraulic roller cams, for which the heads were originally intended.
More good news! We can get these results with a 2.02 valve, a special valve and seat job, and very special porting in critical areas only. What this means is we can supply the flow numbers to feed 450 HP at an extremely attractive price.
The only drawback (and it may be a positive for many) is that the porting is not visibly obvious. In other words, you are gonna need to look close to see anything. You cant see much, but you sure can feel it. The exhaust flow is not modified as we feel that it is more than adequate for the intake flow available. These super prepped heads have small port volumes and are suitable even on stock engines are they the perfect head for Magnums? Could be! If not, they are very close, at this time!
