F303
I have a 1995 302 with aluminuheads they say svo on them and appear to be gt40 heads on the computer there stamped F3ZM-6049-x302 but the roller rocker are not adjustabl.I have an F303 cam and hydrolic roller lifter but not if I need to change the springs and will the the vaulves hit the pistons?I was told it was crate motor but with plastic lifter retainers and non adjustable rockers could be just a 302 with bare aluminum heads with cheap rocker arms and springs.

What is your goal for this engine?
I had a Mustang Cobra that I put those same heads on. With headers, stock cam, ported intake and bigger Mass air and headers it made 275 HP at the wheels. If you use that cam you will loose any low end power and will need to spin the motor to 6 grand to make peak power if not higher.
