3 More Questions

Hey I've got a 1990 fox with trickflow stage two cam, trickflow intake 75mmtb 42lb injectors 255lph fuel pump, and vortech v1 super charger with aftermarket pulley. 8 to 10 psi. All this is riding on some stock heads so 4700 rpm I cut seems to Float valve or make the valve springs make out. Are these a good head and what size rocker would be recommended. 1 answer

• The Edelbrock Performer Cylinder Head would be a good cylinder head for this combination with a 170CC Intake runner. I would recommend a 1.6 rockers for this setup.

Good cam to match? Just looking for a good cam that will pull up until 6000 rmp 1 answer

• I would recommend the Ford Performance B303 Performance Camshaft (85-95 5.0L) for some good low-end torque, a significant increase in top-end power above 4,000 RPM, and a fair Idle.

what other mods would be good to do with this bolt on? 2 answers

• Some good mods to get peak performance out of the heads would be cam, 1.6 or 1.7 roller rockers, intake & larger throttle body. Stick with the Edelbrock intake RPM II, as it has one of the best flow rates. You might consider going up on the injector size as well from the stock 19mm. You should probably need a new MAF sensor to handle the increased TB size and intake.

• Along with the above mentioned mods if you still have a factory fuel pump make sure to upgrade it to at least a 110 LPH and an adjustable pressure regulator. A cobra/explorer 5.0 intake will also work excellent with these heads.
