Tta heads

[Wicked WE4]

Will 89 TTA heads work on my 87 T-Type? If so any modifications required?

believe the exhaust ports are different so it will require different headers.

89 tta are totally diffrent than regular buick heads.first off they are basically a fwd head EXCEPT tta heads have unique part#
the manifolds are totally diffrent and the crossover is diffrent as well.

no benefit to try to make these work on your car! it would be a waste of time and $$$

if ya get the heads and the manifolds not much of a problem other than getting a downpipe made to fit (Oh did I say I have a downpipe for that set up :biggrin Personally a waste of time and $$$ to me.
