I've heard mixed opinions about dart heads....

[RedDemon2]

Anymore opinions??? Thinking on going with the Dart Heads and just want to know if they are worth the price.

i have a set of dart iron eagles on an sbc 350 and i love em, they r a great head and i got them for a great price, they only thing im planning on doing is port matching the heads to the intake.

The Dart LS1 Pro 1 heads have the following features.

1. They flow well as cast.
2. They have one piece solid stainless forged valves made by Eaton who makes valves for most of the name brand companies. When I had mine apart, the valves were marked as REV CL 1158 adn CL 1170.
3. Beehive springs that are nitrided made by PSI. PSI makes a lot of the NASCAR springs. They don't have a lot of history on a street application though, as most people run the Comp 918's when they run a beehive spring.
4. One piece valve seals/seats made by US Seal who also makes the GM seals used on the LS1.
5. Machined locks on the valves.

For the price, not sure how you can go wrong. I bought mine, disassembled them and have just lightly cleaned them up. They should work well out of the box
