Will pre tbi heads fit a tbi engine?

Yes, pre-TBI (Throttle Body Injection) heads can fit a TBI engine, but there are some considerations to keep in mind. The compatibility largely depends on the specific engine model and the intended use. While you can physically mount pre-TBI heads onto a TBI engine, differences in intake ports and combustion chamber designs may affect performance and tuning. It's advisable to check for proper sealing and alignment to ensure optimal engine function.
