Ive searched and came close but found no answers. I'm trying to find a set of 14101083 cast numbered heads. I found a set at a Salvage yard with this casting number. But it lists the donor car as a 87 Caprice. Are these heads still good for a 90-92 TPI manifold??? I don't want swirl port / TBI heads or anything else I have to modify to get to work. I know the center two manifold bolt holes area different angle, Would it be the same on both a F_body and the Caprice head due the casting number or should i keep looking for a set from a f-body?? Any help would be greatly appreciated!!

 

The heads don't know which car they came from. They should work fine on your later model TPI. Some bowl blending on those heads will help it a lot before you install them.

I've never had to bother with the bolt angle adjustment as a result of the intake I use...but I thought the angle switched over in 87 to the later style. Maybe I'm mistaken.
