I just purchased these heads would the work with the e 303 cam and performer 2 intake? Also I got the valves with them but I need the springs and the 1.6 rocker where would be a good place to get them?
They will work with the performer and performer rpm intake and E303 cam. If your car is 1986, be sure to check PTV (piston to valve) clearance. I used Scorpion Racing pedestal mount rockers, 1.6.1 ratio. LMR offers some rockers I believe. Paired with a 600 or 670 cfm carb and good headers with free flowing exhaust, you'll have a great combination. LMR, Summit Racing, Jegs are some other sources for springs and rockers.
