Five7kids, Did you notice any difference and about how much HP did you gain?

Haven't gotten it together yet. Too much business travel this summer.

I'm making so many simutaneous changes that it would be difficult to quantify how much the porting itself helped. But, even World recommended bowl work on their parts, and every mag evaluation I've seen of them had them pocket ported.

This is my first attempt at porting (I did a gasket match once). I didn't break through to water or oil, didn't nick the valve seats. This by a person who trips on basketball court lines...
