Re: Intake ports, Oval or not?
Unless someone has changed the heads and intake oval ports would be the ones you have.
You can always verify whether or not the heads are oval port or not by looking up the manifold casting numbers on your engine. Or the head casting numbers, (under the valve covers) can be used to verify whether they are oval port or not.
