has anyone heard about those world heads
 

im lookin at some sportsman 2 heads by world and i dont know if they are any good
any suggestions

I had good luck with the ones I had...

I bought a set of the original Sportsmans back in like 1991 or 92. I liked them. I still have them on a street car.

A friend bought a set about 7 years ago-used. Spent almost as much rebuilding them as a new set cost. Good head, but he wished he would have spend the extra $100 and just got them new.
