Intake Manifold Bolt
Hallo guys !!!
Today I tried to bolt my intake manifold ( from a 1985-TPI-IROC ) on my new 1987-engine ( with 1987-heads ). But what´s that : The 4 center bolts won´t fit. Does anybody has a solution for me, how I have to modify my intake ? ( A picture would be nice ).
Thanx, Uwe

The 4 center bolt holes are at a different angle than the older style heads. They go straight down into the heads when the engine is assembled and put together.
You have to elongate (make oval) the 4 holes in the intake manifold.
Just think of it this way.
