Just bought some gt40 heads for $ 50.00 bucks they need to be clean I don't know what springs are on them what's a good combo for my car.all I have done is full exhaust pulley s cold air intake.373 gears.so when I do the heads there we'll be a cam going in and a gt 40 upper and lower intake with a 70 mm throttle body.thanks for your input
