small block heads, 4027596 casting # any good??

OH, I'm not here to split hairs and argue. I thought you were for a second, but I see not. Generally, I agree the X head is a better head for many applications up to and including porting, but at the OE posters level, why spend the money on what he allready has will do very well.

Your posting isn't exactly a apples to apples.

I'm done here. The kid has alot to chew on.
