Aluminum cylinder heads

that's an expensive 30hp though comparing the cost of both heads and if it's not a race car it won't matter as much.
neil.

There are deals out there.... I have a pair of TF240s that didn't break the bank - I found a source for factory blems and then bought valves, springs, retainers, etc -- dropped them off at my machinish - Ended up costing ~$1,400 for everything -- not cheap but definitely not as much as the $2,400 a out of the box pair would have cost and only a bit more than the E-streets --- having worked with both Edelbrock and the TF heads I have to say I am more confident with the TF heads over the Edelbrocks
