TEA 6L stg 3   [email protected] not bad for 1850 bucks :driving:

Got mine for $1650 on a group buy and flow just a tad higher.

whats the difference in yours and the ones listed on teh site?

Nothing. All don't flow "exactly" the same, although close.

The difference is that that Benkeys are stage 3 with a 15* valve angle and ET 225 are stage 2 with a 11* valve angle. with almost identical flow numbers at .600.

 

If you do a true comparison with TEA and ET heads on identical truck the ET heads with produce better 1/4 mile times.

Maybe.

 

Right now they are just a pipe dream for most.

yup. no definitive results yet. hopefully I'll be upgrading to some ETP's from my 5.7's on my CSS in the future. I would expect to pick up upwards of 40rwhp.

Heads will be in tomarrow, being shipped over night. I'll have some pictures posted up on Monday of the set up. 90mm tb, Fast intake/ fuel rails, and some other tricks up my sleeve. Hope these heads are what everyone says they are. We'll see.

for as long as they took to get to you they really better be

Finally looked at their website.

 

Since there are no 1.60" exhaust valves in these things, usually what separates the stgII or stgII.5 from a stgIII, I'm assuming based on their options page to get you to a stgIII you just get springs good for .650" lift? Way I read it.

 

My heads flowed, TEA heads, $1850 w/.650" double springs

.100 70.5 51.1 All measured on a 3.900" bore

.200 145.6 117.0

.300 213.0 171.6

.400 268.1 230.3

.500 307.2 257.5

.550 321.3 262.5

.600 337.4 267.7

 

ETP 225, $2475 + $185 for .650" springs, total $2660

.100" 71 57 All measured on a 4.000" bore

.200" 153 114

.300" 208 164

.400" 265 204

.500" 308 224

.550" 320 228

.600" 328 231

 

ETP 240, $2650 + $185 for .650" springs, total $2835

.100" 73 57 All measured on a 4.000" bore

.200" 152 114

.300" 210 164

.400" 266 204

.500" 312 224

.550" 327 228

.600" 338 231

 

The only one of these ET heads that measure to the TEA heads are the ETP 240s. The TEA heads were flowed on a 3.900" bench, therefore numbers would be just a few higher flowed on a 4.000".

 

I guess I am personally not seeing $1000 in difference when you compare flow. The TEA heads would easily outflow the 240s if measured on a 4.000" bore. The TEA exhaust flow numbers blow the ETs away, but I'm sure that is due to the smaller exhaust valves of 1.57" compared to 1.60".

 

So what is the big deal on these heads? School me. Is it "supposedly" velocity, volume, or what? Are there any dyno results that showed they are better than any other out there?

 

Not dogging the head, they are nice. I just don't get all the putting up with the wait (3+ months) and what seems to be exorbatant cost.

 

I shaved off the .6500 and .7000 numbers. They won't mean jack to 99.9% of us (although they were good numbers). A .620" or so lift is the highest I have seen on here yet.

 

I also didn't mention that the TEA LS6 stgIII head, same price - $1850, you would need to go a step higher to a 255 to exceed in flow - but again measured on a 3.900" bore.

ok, here are some of the advantages.

 

raised rails so you can fit aftermarket rockers without expensive spacers or valve covers.

11* heads to fit bigger cams without flycutting pistons.

thicker deck to help agianst lifting or warping a head.

 

I don't buy the 3.9 vs 4.0" bore flow analysis. going to the bigger bore doesn't provide that much more flow. I would guess your TEA's are between 235 and 240cc, so the 240 would probably be the best comparision.

Okay. It would just have to be air differences - how it flows, velocity, how much, etc.. Valve cover spacers cost only $100, but systems like Crane race golds you can still use the stock valve cover height. The larger bore will flow slightly higher. Not much, but a few more cfm.

 

I like the idea of it being it's own cast and not from a stock cast. The fly-cutting thing - don't think that is an issue for truck guys. My cam is 236/243 and didn't have to. Can't see many going too much more than that. I think this part applies better to a car, but may be wrong.

 

I was just trying to figure out what a thousand dollars difference got you. More flexibility is one thing, I guess. Do they offer any bigger exhaust valve than the 1.57"? I didn't see it on the site anywhere.
