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.
No, they don't. 302 are small like any other 273/318 head. Mayne you mean 308? The gaskets are one size fits all after a certain year for LA. Early stuff they had 2 gaskets. Later on they decided to save a penny..
