| Touring auctions and digging through junkyards for a good set of Vortec
heads can get old. Pro Torker™ Vortec Heads are designed as a stock replacement
for the popular GM 906 casting but flow far better and are much
more powerful. RHS® patented Clean Cast Technology™ and close tolerance
machining provide exceptional finish quality for superior performance and
reliability, and the revised water jacket design helps prevent cracking commonly
found in GM 906 factory castings. And when you add up the money
you spend repairing and machining factory heads, these heads actually save
you money - giving you maximum power for your performance dollar. | | | Made from quality cast iron using patented Clean Cast Technology™ for racing classes where iron heads are required | | Standard features include hardened radius exhaust seats, multi-angle intake seats & "Fast Burn" combustion chambers | | Equipped with 1.550" valve spring seats & valve guides to avoid retainer-to-guide clearance issues when used with high lift camshafts | | Available "as-cast" or assembled (#12410) with COMP Cams® components; 170cc intake runner sizes & 64cc combustion chambers |
