Magnum Exhaust Port Dilema

No, 302 heads have regular 318 port exits. Use magnum exhaust gaskets and don't mess with those Magnum ports.

I've owned 302 castings. They have the same ports as the 360 heads. The blue colored gaskets are 273/318, the other is a 340/360 manifold gasket. It is the main reason I switched to 302 casting on my 318. The exhaust ports are larger.
