Forgetting about the prices. Which head do you guys think would work better with my blower setup?

I'm thinking the trickflow cuz it seems to have better exhaust.

I'm also not sure how the 140# springs on the Dart's will work with my roller lifters..

Dart heads are available with many different spring packages from mild to wild. Don't base your decision on that. Also, Darts are available in a variety of intake runner sizes (180, 200, 215, 235) and a variety of valve sizes. Lots of options on the same basic head.

Both heads would probably make an excellent choice for your application. If you decide to go with the Trick Flows you should be aware that they require special length pushrods where the Darts do not.

 

If you are going to spend that much, get AFR's! Dart's are good too!

 

AFR's for around 1,100 ??

Everyone seems to think darts are great, but the flow numbers just arnt there.

i agree

 

I know I'm asking advice and at the same time being opinionated cuz I did my research on this. I understand teh pushrod and spring combo, so I'm getting a quote from racers outlet on the pro1's with the correct springs..

So money asside, and just on these two heads.. Which is better ?
Cuz the flowtables all seem to point at trickflow. even desktop dyno shes the trickflow being the better head.

I'd think especially since it has a better exhaust flow.

the push rod thing is no big deal (i have tfs 195s on my car ) you'll need new p-rods with what ever head you use...

I'd go afr's or tfs heads. You'll still make good power with the pro-1's too if you go that rout

what blower you looking at

 

I'm running a vortech s-trim, but thinking of upgrading to a t-trim

 

If you beleive the flow numbers you have in front of you then get the Trick Flows. I haven't used them myself, but I've heard good things about them. I HAVE used the Pro 1s and they're a solid choice. Sometimes from numbers don't tell the whole story. I once replaced a set of mildly ported S/R Torquer heads with a set of box-stock Dart 200s and proceeded to drop 4 tenths and pick up 5 MPH with no other changes whatsoever in a car that was already running bottom 13s on street tires.
