I have not seen many results from the Trickflows on a 383 yet. I can say down here we have had 2 cars running the Dart heads. I had the 205s, with only milling done on them with my 383 and the car made great power. Another car had the 225s, and his engine was always running slightly better than mine was. I would not expect you to be giving up much more than 10 rwhp between the two sets of heads. In the end the Trickflows will cost more due to the roller rocker change and the longer pushrods needed. If you are going to run the Darts you can often reuse your current hardened pushrods.

nothing i don't think
assuming you're talking about the ls1 versions.
as for power...with that very mild cam...i would think 450hp and 430ft lbs....all peaking pretty low in the rpm band.
something to consider is that by going with the TFS heads....and the needed rocker change. you could put a set of Comp 1.75 rockers in place of the 1.7s that are stock. it would boost your lift a little to take advantage of the flow potential of the heads.
lift would end up at .586/.579"

If you are gonna port them later on a T4P job on Dart 225's can get you 346cfm which I don't think you'll see from another cathedral port head. If you plan to run as is the TFS is prolly a little better.
I have read some head guys on other boards report that Dart valve jobs as is can be pretty bad and need work outta the box so that might offset some of the RR cost of the TFS.
That is a KILLER deal from SDPC
I WISH they were running that when my setup was going together
Sounds like it will be a nice setup so I hope this doesn't offend you but you are leaving a lot on the table with that cam.
A 383 can run a cam about 5* more duration than a 346 and maintain about the same manners. I don't usually recomend cams and leave that to the experts on here but I think you could run a high 230 intake low/mid 240exhaust and have a killer setup still with good manners
The main thing is that reverse split cam you have is not very good for N2o. N2o likes a traditional split and the larger exhaust duration of a traditional split will help the motor expell all the extra gasses produced by the N2o hit. The114 LSA is good. Make sure you mill the heads to the desired CR cause nitrous loves that too......
Keep us posted!!!!!

i definetly will keep you guys posted and that is a great deal from john. That is what i want to do so now i just have to make sure it is possible for me right now without puttin me in a bind on other things ya know. Im in the car business so we all know now is truly not the time to be doin a build ya know. On the cam, it is kinda small and i would like to do it up to but i definetly cant do it all at one time, I will go back for the cam i guess. I started this just to do heads and no intake and throttle body to but today when john showed me that deal it would be hard not to do that. I just really hope to get as close to 500 hp and some really good torque out of the motor before i spray it. I previously had a 99 ss camaro with a 3.73 gear, lid, no motor work, stock manifolds, stock intake, et streets and a 150 nx shot that went 11.65 in 1/4 at bristol and that car was just a freak, so it kinda ruined me on what to expect i guess.
