340 x heads

Why not cut them up? I guess that's my main question. My dad is telling me to just go for it as they flow well to begin with and porting will only help. And it's cheaper than trying to find newer heads. This is a budget build, I'm using what I got.

Also, Rocky what's the point of that link? All they did was work on the 360 heads until they exceeded the 340s. If you put that amount of work in the 340s they'd flow the same. I got the engine for $500 with the heads on there. I'm not blowing money on it if I'll get the same result for less money.
