stage 2 heads

[V666]

How much can I pickup a set of these heads for? and I guess the intake and headers also.Is there anything else I need.

[Buzzard]

You will also need, rocker arms, stage two cam, offset solid roller lifters, pushrods, stage 2 valve covers, headers, and some one to help with the setup if you haven't done one before. :aaiconbeer:

I have a stage 2 motor with a roller cam. just has the gn1 heads with chevy style 1.65 roller rockers, tall valve covers. Is it worth the time and money to change it to the stage 2??

[Otto J]

You still must change the cam when going to stage 2 heads,different valve configuration.

[V666]

Oh that makes sense my bad. Are the gains of the stage 2 heads worth the money. I am told my setup is good for 9.50's what could I expect with the stage heads?

[gnxtc2]

And a different intake. Basically the top portion of the motor needs to be changed including the cam.

If you are already set up with the small heads, you have a decision to make.

What kind of power are you looking to make? Guys have run 8.5's and speeds in the 160MPH range with the GN-1's.

[V666]

thats all I needed to hear thank you. I'm only looking for mid to low 9's. Thank you.

[Otto J]

Than stick with your champions,mid 9to low 9s no problem

[V666]

cracked my gn1's looking into maybe picking up a fully ported set of TA heads anyone familiar with these. I just have had two many problems with champion gn1 heads(2nd set with issues)

A few guys running TA's and so far so good, there is more meat on them. I do not know anyone who has had any issues, remind me of S2'S.

[V666]

thats what I hear , I also hear that they are taking over! Figured I'd ask the big dogs on here. supposedly theones I'm looking at are 3,000 and can support 1500hp does that sound right?

[Otto J]

How fast has anyone run on TA heads to date?
Anyone taking them to the extreme yet?

Full blown Race Ported with rockers and shafts are close to $5000.00:shock:

I do not think so, a few mid 9 sec cars. To early to tell, but they look promising.

[V666]

I have T&d rollers already and looked into full blown race ported with vavles only. everything else is supposed to fit. The heads use diffirent valves because there's more meat on em. SO I"m told!

[Otto J]

i think they require special rockers,not the older t&D style

[V666]

ok I'll look into that and post when I find out but I was told the shop checked and they just need to be shimmed correctly so I do some digging and if any one else knows please post on here.

Flow bench numbers are comparable to the GN1R heads with a substantial improvement on the exhaust side over the GN1R's. This is on the SE heads with the paired shaft rocker assembly. In our testing we feel that the TA heads will hold up to more abuse due to the nature of the design, ( more material in the deck surface ). As soon as Nick gets the motor together to go with the Huge turbo he just bought we will be pushing these heads to the limit. So far there has been no issue with cracking at all, the 14 bolt champions have a history of cracking even at the mid 9 level.
I think the TA heads would be a good choice for your combo. :rockwoot:

[V666]

sweet sounds good I'm trying to run high 8's to low 9's

[Ted A.]

I would like to see some big HP made with these TA heads, such as high 8's for a period of time before the comments that they don't crack hold any water. I have had good luck with the Champions so far, not saying the TA's may not be better in the long haul, but we need to see a set get deep into the 8's and hold up before it is safe to say one way or another.


How many cars have seen the mid 9's so far for any period of time?

On a flow bench the champions ported show plenty off exhaust flow sometimes too much compared to intake flow.Intake flow is where work is needed from what ive seen

Ted the heads are relatively new to the main stream so I think(like you said) we will have to wait and see, but they look promising. After speaking with Tom his heads were never designed to go into the 8's, he has constantly had to improve the design to keep up with the power some are making:shock:

[V666]

personaly I am not happy with the gn1 heads. I have had 1st gen and 2nd gen and had problems with both. I don't and won't be burnt again. Not that there won't be problems with anything in the 8s or 9s. I'm gonna run the TA and hope for the best

What class and what were you running ET wise to smoke a few set of GN1'S:confused:

[V666]

well the first set was the old style with stock rocker and I lost almost every thread from every hole even the helicoiled ones. Second set melted out due to not being torqued correctly then cracks were found across the main body of both heads. I was told this is a weird crack and not anything I did! So I'm not a big fan even though it might not be totally champions fault. The car has run 9.97 @138 and should be capable of 9.5's

[Buzzard]

After Indy we may see some more of the heavy hitters running TA heads, as Champion and TA both have heads that can flow the big numbers, it all comes down to who is the most reliable IMHO. We shall see.
