Re: Intake Manifold question

In the late 80's (87 or 88) GM started using TBI equipped motors. The heads and manifolds are different. It's easy to check. With the manifold off screw a bolt into the center holes. If they stick straight up instead of angleing towards the center of the motor the heads are TBI. These heads also use center bolt valve covers.

I've seen guys modify manifolds to work, but they're kind of a hash job. After market manifolds are available for a proper fit.
