I sold my TPI to a friend, he lives in Texas, I live in Illinois so we both missed some important points about his engine. He has a newer Vortec crate engine and the heads only have 4 bolts per side and they are not angled, has anyone ever modified an early intake to fit these heads? Can it even be done?
I don't think it is going to work. He will have to buy the Vortec manifold.
The angle on the heads for the intake is a different angle than the standard 350 Chevy heads/intake or the L98 TPI intake. I don't believe that you can machine the intake with the new angle...there is not enough material to accomplish this.
