These heads are tapped for the old andnew type intake manifold, also perimeter v/c or centerbolt v/c.

Be weary of the dual bolt pattern though. We put a set of those on a '91 Formula and the intake ports were taller than the stock TPI intake casting. Meaning the with intake setting on it, you could see about .030" of the top of the intake port. We had to order a Vortec TPI base to make it work. You could get away with a Wieand Team G or a Victor Jr that have bigger ports and raised casting, but don't think you can put a stock intake or even a Edelbrock Performer on there and go. I will not work. The intake ports are about .170" taller than a normal stock SBC port.

Otherwise, they are wonderful heads. That 'bird is one the stoutest N/A TPI cars you'll see.
