302 casting potential?

When it comes to the W2 exhaust port reference- I believe due to 20 something years of the same 340/360 low floor exh port, people tend to call any mopar exhaust with a good raised floor 'w2 style'.jmo

But really...They wouldn't come anywhere close to what a w2 exhaust flows.

when you get 1/2 inch tall then layed back type floor from the seat, then you have something 'like' a w2 exh port.jmo

I took a look at the numbers that ryan J has in that link you posed for 302's and J heads, and it seems like the J heads have a decent amount more flow...but flow is not everything right? or alteast thats what i read...and man, i wish i knew what you were saying about floor and seat and stuff lol...i think im gonna look for some sort of cylinder head walkthrough video or something, since i need to understand all these terms and such
