Thanks for the reply guys . I think were my mistake on headers was the fact that I bought shorties instead of eqal length . My shorties I bought when I put them on I cannot put my starter on . So I think for the time being I will just find a pair of manifolds and put on . As for the wiring and everything goes I am still a little puzzled on that . Do you guys think maybe a buick regal auto guide would have a wiring harness diagram ?
