has this head been ported? (4age)

May or may not look a bit like this....

If it was ported and polished the internal port surface would be a lot smoother
and have a.... um... polished look

This one has been sitting for a while, but you get the general idea.

looks like it been deburred.
but as said.. the port divider looks untouched as do the valve guides. if thats a bigport, you wouldnt want to port it much anways, they're already huge ports. how bout pics of the chamber and valve bowl looking thru the valve seat
