Just got my ported l92's in from TEA.This is there Stage 1 port job.I also had TEA replace the stock 2 piece l92 valve with the 1 piece hollow stem ls3 valve,exhaust valves on both engines are the same.It has the platinum dual springs and ti retainers.I also had the heads milled from the stock 69.x to 68cc.

Flow #'s are:

intake exhaust
.100 74.4 58.7
.200 153.6 124.2
.300 228.0 177.1
.400 290.2 214.9
.500 332.6 246.9
.550 346.0 257.8
.600 353.8 265.4
.650 362.1 270.1
.700 370.9 274.7

And thats on a small bore(4.030")











I have read that ported l92's seem to hit a wall after .650 lift,my flow sheets prove that is certainily NOT true.

This will be going in a 2005 Escalade EXT with a ported l92 intake,a 9.3-4:1 compression 408,60# injectors,built 4l65 with circle d 2600 stall,and a 224/236 .600ish lift camshaft.I figure the lower compression will allow me to add forced induction or a good nitrous shot if it isnt fast enough NA.I will be happy if it makes 425 all wheel hp.Anything over that is gravy!

Almost 50 views and no comments???

I would figure people would be coming out of the woodwork since l92 heads are not supposed to pick up flow well over .650 lift:dunno:

Are these good flow #'s?From what ive seen posted on here,these are AWESOME flow #'s for a set of ported l92's flowed on a small bore.....

How many holes are in your castings???There are quite a few thin spots in these heads and the set I have is about as far as they can take l92's without a ton of welding.There is no way they will flow more than these without welding,sorry,its impossible,esp.......Several of my rocker arm studs will have to be installed with the right stuff as they broke thru when porting.Nothing to worry about to me as every set of max ported Buick Grand National aluminum heads I have seen are the same way.

Who ported and flowed your heads?Unless it is a MAJOR company with a known good flow bench,Billy bob who does all the pro stock stuff might know how to port heads but anyone can fudge the #'s.

I will pay your shipping to and from TEA if you let them flow your heads.And I will side bet they dont flow near 400 cfm.That is,if they have not been welded on.....

WHAT????? I'd like to see that in person.

Best hand ported L92's I've ever personally seen flowed did 365 cfm @ .650 and 274 cfm exhaust @ .650.

He probably has a small turbo on his flow bench forcing the air through....

pwebbz28's L92's:

.650/369 254
.700/377 257

People are getting upwards of 275 cfm on the exhaust side at .650 lift with L92's with just regular hand porting and not using custom sized valves.
Wonder why these are 20+ cfm less.

Heads that flow 370cfm on the intake,like these ported TEA's will support over 900 flywheel hp NA.Theres all kinds of things porters ca do to get high flow #'s,esp when charging thousands of $$$ more for a comparable product.

I did a bit of research before I sent my heads to be ported and TEA's flow #'s were the highest I could find from a major supplier.Also,TEA must be constantly refining the cnc program because my heads are flowing more than advertised.

have you had them on an independant flow bench?
a friends shop flowed a set of tea heads and they were 30fcm less than advertised.
im not starting any **** here, every flow bench is different. just like a dyno.

Seeing as they flow 350 cfm from the factory,I dont think so....-30cfm would mean they dont flow as good as stockers...

Friends shop in Pensacola?Well theres your reason right there...There are very few people who should be trusted flowing heads....in the south,there are only a handful and none even close to you......get a good shop to flow your heads and see if there is a 30cfm difference....Ill bet not...

So what did your L92's flow when stock on TEA's bench? I would be curious to see how much they gained over the stock flow numbers. I have seen stock flow numbers vary from 313 to 34x on the same casting, just on different benches. FWIW a set of stock LS3's flow 322 on my bench (Superflow)

the difference was on a set of cathedral port heads.
im with the poster above, what did the heads flow stock?
if you are so sure your heads flow what they do, but them on another bench.

If you are so sure they dont,you pay for them to be sent and flowed and returned to me....A reputable flow bench,like WCCH or Champion Racing in FL.And well make a side bet they flow within 5 cfm of TEA's charts,say $100?

They flowed 332cfm stock according to TEA on a small 4.030 bore....I have seen MANY post they flow in the 34x-35x cfm range stock,all on larger bores though....easy way to get better flow #'s.

And i know that many,like Patriot,still do not even offer a cnc program becuase they can only pick up a few cfm.Max ported l92's arent going to flow more than 30-50 cfm over stock.

put it on an engine dyno or the track.
those are results that matter to me.

I have seen a few sets flow 328cfm bone stock! And have seen many others posted up on here flow that.
