ok cool I didnt think of that. SO i was able to find the head casting numbers they are 14102193. Are these good heads? I read that they are just stock heads that are not good if youre going to make preformance. Are there any preformance heads that are good with TBI? I also found the intake manifold number 10166133 its also stock but is there a preformance intake manifold that I can still use a TBI on?
