Like Flyer said good street heads depending on what valves are in them and what cc they are. Sounds like if you're heads are already ported and have good guides the Darts won't help you much maybe worst without matching the cam and intake manifold to the new heads. RICK
on the engine you mentioned... will the engine know the difference... and will it really matter which are used?
ANY performance head will be better than a stock, as-cast Camel. spend a bunch of cash porting etc on the Camels and they can be as good or better than "some" out of the box perf heads. now spend cash on the perf head with extra porting etc and now that head is again better than the Camel... Darts, Brodix, AFR's etc are pretty much better than an as-cast or ported Camel out of the box.
your engine will notice the difference immediately, but whatever performance differences from the darts to an AFR... you'd never know it...
so what i got from that is there will really not be any difference in performance from the ar and the darts. but i will see a big difference in performance from the hump heads? thank you for all the help, i want to learn to build engines and work on cars. i am 19 and no nothing. my dad was a machinist but he died when i was 10 months old. he raced a 64 nova (my unlce races it now) and i live 14 hours away from everyone who could teach me. sorry for putting the sob story i was just letting you know why idk anything.
No problem thats what we are all here for NPHNP! X2 on what Flyer said. Heres another option that are some really good heads for good price. You will have to buy a matching Vortec intake manifold. RICK http://www.summitracing.com/parts/NAL-12558060/
thanks you guys. i am going to start with the little stuff. if i get heads i will have to pay somone to put them on i would rather do it myself or someone i know besides someone idk.
those are a good price on those heads, what about these? i figured the bigger ports the more flow http://www.summitracing.com/parts/NAL-25534421/
the engine is a fresh build. my uncle has done all that. he builds the race engine and he runs 9.80s in the 1/4. the bottom end only has 30 miles on it. the heads are the last set of heads my dad ported, idk how good they are.
