So I put in a set of Rocket Motorsports SL Lite springs and retainers into my b16. When I was installing I realized it must have been an automatic head because the intake side only had one spring. I didn't replace the spring seat locaters under the valve springs and now I'm thinking that may be an issue. Will the spring seat locaters be different and incompatible since it's on the intake side? I already have the car back together and it seems to run fine but I need a definitive answer if possible so I don't have to tear it back apart. Thanks!
