Dart heads - off topic (sort of)

[The Punisher]

I am assuming you mean the cast iron dart2 heads by world products?? 
probably sportsman or sportsman2's. I dont recall S/R torquers being 
marketed as "roller" heads.
I have owned all 3 types and can say that they are FAR SUPERIOR to an 
origonal chevy head. The difference in out of the box sportsman's is the 
valve springs and pocket diameter cut. get the roller heads. The larger 
springs will be much better at an equivelant seat pressure.
BTY the metal is very dense and hard compared to the oem heads. They are 
tough. last time I had a valve job done on sportsman2's the guy said that 
the intake seats were almost as hard as hardned seats(this may have been 
exagerated somewhat).
Dart2's are not the best aftermarket heads out there, but in used form they 
are a good value.IMHO :)
