Would the VZ-VE Alloytec race harmonic balancers (Part PB621) fit straight on to the LLT and not on LFX?

The Alloytec race harmonic balancer will also fit LLT and LFX engines. The Alloytec race harmonic balancer kit will fit an LLT engine but not an LFX though. If you're after an LFX balancer kit, please refer to the link below:
