Well, i have been working with TEA to figure out a set of heads. they have been more then helpful, i recomend to anyone to deal with them. they where super to deal with this far. cant wait to get my parts.

anyway. they ended up doing a set of trick flow 245's for me. they just hit me with the flow numbers, and im pretty happy.
pretty sure i should pick up some good power over my old heads. cant wait.

they ended up flowing 360 @ 600 and 272 @ 600

thats a pretty good gain over my old heads, so i cant wait to get back up and running. should have the heads and wheelie bars next week. ready to run.

 

wow...sound awesome. Lucky you!

 

Take the blue pill !

.....

 

Is that on your 427? What do a set of those run out the door if you dont mind me asking?

 

ATV, i dont need no blue pill yet. im a young buck still.


yes, thats on my 427. they run around $3,000 set up for solid roller depending what you have tea do

 

Just messing with you.

Good luck with the new combo!
Who flowed the heads?

 

if you ever get a flat tire at the track you can take those flow numbers and fill the tires back up anyways where did the heads flip at and what was the rest of the numbers past 600? do you still think a cathedral port head can support a 730 lift solid roller cam?

 

Interested to know as well. However...just the fact that they may flip at a certain lift is only half the story. It also depends on how they flip. I have seen heads that take a NOSE DIVE at .620...and I have seen some heads that slowly taper at .600 but only lose a small amount or nearly maintain those flows to .700.

Also with the head bolted to the intake...it can still be difficult to figure how the stall will affect flow at high lift.

I ahve seen some Meaux/Futral heads that had flow numbers that continued to climb all the way to .750. They did seem to be somewhat reduced at midlifts...but they did flow to .750 and were cathedrals and performed very well.


Definately interested to see what this setup does NA.

 

well I have never seen any cathedrals go too much past .675 (and those were the good ones)without them going turbulant and between me and a few others we have flowed alot of heads, all on the same bench of course and from what I have seen cathedrals cannot support 700 plus solid roller camshafts, maybe thats the reason ETP doesnt even make them any longer, they got smart and started working with the square port design. I am stil interested in what the TFs heads do past .600, I know what the 215's and the 225's did and I can tell you it wasnt in the same zip code as what noyzee posted, not that high lift matters, power under the curve is more important but you will need a head to flow well up top to support a big lift solid roller camshaft

 

not sure on all the numbers. they are sending the flow sheets. tea did the flow on the heads. i will probably throw them on a beanch when i have down time. as of now i just want to get these on and get to racing.
im guessing i will not loose any power with these heads over my out of the box afr's and for the money if i get 1 tenth out of the heads on motor im happy, the heads didnt brake the bank, and should work for what im trying to do which is go out and have some fun racing.

as for na, im not set up for "all motor" but it went 9.9 last year and i didnt change anything besides heads, and headers. i removed some weight, but im pretty much going to even it out with the wheelie bars etc. so we will see soon if they work or not

 

I know with shiz's car he saw a 25 horsepower increase after putting on those 2" headers, you should see that or a lil more having a few more cubes then him, either way good luck with it and keep us posted

 

we shall see soon i hope. i will for sure keep it updated

 

Port stall causing loss of top end horsepower is an old wives tale, made famous by cam makers and people that don't own dynos that can't do back to back testing.

We've had heads with killer mid lift flow from .300"-.500" that stalled after .600" make 2 HP per cubic inch with .700" lift cams.

Interestingly enough, a head guy at a Cup shop said the heads they had make the most power flowed killer from .300"-600" but stalled after .600" and they run around .700" lift.

You can flow heads and compute the "area under the curve" using the formula in the article below. I've always seen heads with the most area make the most power, even if the port gets into stall. This article was published in a national magazine in 1996. It is amazing to me how few use the information that is available.

Even more amazing is the shops that don't have the proper equipment to flow heads, such as doweled flow plates and fixed radius entrys. We have 5 flow plates JUST for LS heads, 3.8/3.9/4.030/4.125/4.185 with MATCHING bore sizes. These plates accurately locate the chamber over the bore, trying to do this using any other method is simply a waste of time. To take flow numbers as gospel that are acquired using inaccurate methods is ignorant.

Good luck with your new heads, keep us posted!

 

thanks for the input. cant wait to get them!! im not one to give much of a crap about flow numbers and dyno numbers. im one to take it to the track and try it out. again, thanks for all your help you guys get an A++ from me. i mainly delt with Mike, and he was a great help and very patient dealing with me

 

Brad.. Awesome way to kick off the year...

 

this guys are awesome, they did my heads on my TA and I love them.Thats why i'm gonna use them on my camaro

 

thanks guys. got the heads all on last night, intake on, pretty much all set. i over nighted push rods so im hoping tonight after work i can throw the new headers on, install my rockers and button it up and fire it up. we'll see.

this is while doing a heads/cam/converter swap on a friends car. started that monday should have that done for the weekend as well as mine while working 50-60 hrs a week. im getting to old for this ****
