PRCs/AI 243s/Dart Pros?? Im up the air about heads..just looking for some updated thoughts. Iv read A LOT of negitive things about Dart Heads, but they are older posts. I have a chance to get a set local, They are the 205s. The Darts are cheaper than a set of PRC 2.5 LS6s and About the same to get my 243s sent to AI. For a street strip car, lookng to make as much power as I can obviously, and then a 150 shot what would be a better head for the money?

Iv got a set of 243s now, and talked to AI and TEA Both today on the phone. AI sounds like a winner for sure, but Im worried about turn around time, Im trying to get my car ready for the LSFest in Sept. Still need time to tune it and make sure I have no issues ya know

PRC heads are worth the money if you don't already have 243's.
TEA did my 243's and I think they're one of the top CNC/PP shops around, you get what you pay for, there a few hundred more than AI.
To do it over again; Trick Flow 220 as cast at $1800 are the best bang for the buck IMHO and they can be CNC'd latter for more flow.
Heads are not a place to save money. When I was researching a H/C/I combo, the #1 thing was always heads and flow numbers on any engine that was performing. If you look at the big names; Vigrinia speed has a Vette with crazy numbers, streetable for grandma and a 22X/22X cam. Ligenfelter's cars all had highflowing cnc/pp heads and huge numbers/performance.

I gained 55 rwhp 36lb/ft tq from stock 241s to AI 243s 226cc program... I looked at TEA as well and passed on them.. I also have a custom cam from AI.
If I were you I would just have AI spec the cam for you. These guys have proven to me in countless emails they know A LOT more than some of the "cam gurus" here.

That range of options really covers the entire spectrum of quality & output. It is the machine work that makes the difference, and as always, you won't receive what you don't pay for. 
There are some results & links on our page for the fully CNC'd 243's here: http://www.advancedinduction.com/LSX...cGMLS2Head.php
Many results to add as time allows - right now the other heads need photos/results added more than the 243's since they're probably our most popular CNC'd GM head.
Turnaround on GM LS heads is usually 10-18days if paid in full vs. the 50% deposit. Typically we run heads fairly quickly, and then end up waiting on cams for ~2wk. We try to wait until the cam is in hand & passes QC to perform final milling & assembly so we can guarantee the top-end simply bolts together & has adequate p2v if assembled properly. Thanks for your interest.

if you're going to spend so much money and time on a heads and cam then why not wait till after the event to do the job right? 
I don't understand the hurry when to do a job right will take time to not only get the right parts but to tune also. Plus it's allot of money!!!!
