dont see too many people see over 450rwhp with LS6 heads, damn near 500 sounds crazy. now if it was a 402/408, i could believe this.
LS6 heads can,will and have been making HUGE power for years. You're just use to seeing the Patriot/TSP "specials" that everyone runs and makes sub-par numbers with. Let's not forget that this is a H/C 6.0 with a 4.0 bore being fed by a ported 90/90 and also has an EWP, which is worth a few ponies.
OP,
Great job! Graph looks good! I'll bet she's a runner

I have never known Nick and his staff at Newtech to inflate dyno numbers..Especially for "internet street cred"
Great results..And if you arent buying the numbers im sure the owner or his son is willing to prove you wrong...Great results NEWTECH!!

I missed this the first time around. I'm glad everything worked out for you guys!
That said, I'm shocked people are surprised that we can consistently make 450+ with the GM 243. It may not win flow bench races, but fortunately the engines don't know that. They're a phenomenal option for the $ if you're looking for 450-500rwhp NA.

What do you think AFR and other companies base their castings off of?

The #'s are high but believable. A.I. does great work and they know the 243 port better than most. I picked up 40rwhp with a set of stock valved ported 241's from A.I., and almost 50rwhp from a set of ported 243's on a 6.0L iron motor. They're the real deal if you're interested in racing cars, not flow benches.

It's a damn shame Phil quit answering my text messages. I've done 5-6 sets of heads the past 2 months that had to go elsewhere.

Do you have any graphs you could post for your ported LS6 heads on a LS1? Also I would be interested in any results from your ported aftermarket castings. I checked your website but saw mostly results for LT1 cars.

Indeed I do.
Yep, the website is currently way out of date, and we've got quite a bit of info/pics/etc. to add as we try and find the time to work on it. Just as on the LS2's, going from as cast 243's to our CNC'd 243 tends to gain the same 4Xrwhp SAE peak w/ gains throughout the powerband. We also have a couple 3.900 bore specific programs that we'll try and get up on the site/store for you guys in the near future.

I'm having my 243 heads sent to these guys on Nov 1st. My car currently puts the numbers in my sig with stock 241s. I went with their 226cc full CNC program and PSI component springs. I am ONLY hoping for 435rwhp with these heads. I know that I am low balling myself but I don't want to be disapointed like I was with my FAST lol, only gaining 13rwhp. I'll post my results in this thread when they get on probably early-mid December.
