I got bored and made many changes, results inside

David, told you last night this was gonna be a worthless thread. Beleive me now?
I have a set of TFS 215's sitting beside me and another set coming. Lets throw a set on and let it eat and see some BACK TO BACK numbers!

Sounds like the OP is just tryin to stir the pot.
5 mph in the 1/8 is big, as Tony M stated. But, I can see a crappy converter suckin that much up. not saying Yanks are crappy.
Anyone been around racing long enough to remember the G.E.R. junk?
Now theres a crappy converter!
Not shifting into 3rd, well, that changes everything. And again, makes it look like the OP is just trying to stir the pot.......
i picked up 4.5 tenths in almost identical weather with the same transmission and a tighter converter in my bolt on car. so this thread is useless as far as information purposes-stick it in the drag racing section and get ur praises. 
i would like to see an apples to apples comparo-same cc-etc, back to back dynos.

I am mainly speaking of my ZO6 (see sig) that I will still use on the road but that could race and perform without adding to the engine for the moment...
A well balanced combo for my hp.
I will upgrade to EWP and high flow cat back to play in the Senior (~10hp)
All ideas welcome

*Disclaimer my credentials to post facts*
Comparitively, I build race cars, motors, combos and everything in between. I have run a chassis dyno & race shop over the last 7 years and *personally feel* I have more experience and knowledge on results than the person producing the cylinder heads. If we were talking in depth knowledge of cylinder head development and port design, he would know much more than I in that respect.
Personal results, If you dont agree just ignore me:
I have swapped many th350/400's into LS1 cars. This swap ESPECIALLY with a transbrake will net alot of mph/et gain EVERYTIME. Less horsepower to turn the tranny, better converter setup, leaving on a brake will show gains in both if traction and track prep allows.
I have dynoed several before/after. You always see losses...dyno is useless often time for comparisons from other setups across the country on another dyno. But its a great tool for showing improvements and tuning gains on the same vehicle etc etc...
Soooooooooooooooo the mph gain/et gain from one combo cannot in way be used to show the new heads produced any gains vs another head. Nor loss. No conclusion can be drawn from the head swap period depite the longwinded post on the previous page and now my longwinded post on this page.
....not bashing anyone..
BTW: Congrats on the new ET/MPH improvements. Going fast is all that matters and ill put whoevers parts on that make the most HP. I root for horsepower not manufacturers.

Thats what I'm talkin about.
i see 7 pages of people arguing about heads.
boring.
car went faster..... even if he bolted on a set of stock port 317's from the TEA's with all the changes.
hes just really happy about the car moving out.
bad choice of subject for the thread.
congrats on being 2 hundreths of a second slower than me dave.
hehe.
car looks awesome!

Yeah and the car would be just as fast with cnc'd 243 heads with the same cc chambers. No one EVER just changes the heads in all these so called comparisons. The compression is ussually different as well as the cam. thinner gaskets port matched intakes...better exhausts or intake systems. The truth about heads is that they do not make the difference that the vendors on this board want you to think they do. I do not blame afr, tfs, etc. for wanting to make a living but there is a ton of fudjing and tweaking to make it appear that the "heads added 55 hp" when in reality the heads added 20 hp...the new valve springs added 8 hp...the freer flowing exhaust added 15 hp and the tune added 10 hp...the extra compression and quench picked up a few more ponies. I am not knocking anyones heads and I love trick stuff more than most but I detest bullshitters. A while back one of the sponsers did a back to back on the most popular heads and the differences were very small...so small in fact that an underdrive pulley or an electric waterpump would make more of a difference.
Dave the car has more in her! The Red vette that was there was running quicker with a 4l60,LS6 heads,small cam and converter all installed by me. He was complaining about traction from the 18s 
If you take your numbers x1.56 you are knocking 10s in the 1/4

hahhahaha so the car wouldnt even get into high gear with the old setup! Wow.......most useless comparison ever.
Well I see too many changes to use vendors names in the title. To me that was just to get people to come inside and read. I changed the title to reflect what many have said and I agree..
