well actually things have changed a bit and i've decided to go 383 and right now I'm kinda stuck between the TEA 220cc heads and the AI 200cc package. Something in the 415-420 RWHP range and somewhere along the 430 rwtq would be something along the lines I desire. I want something that is a blast on the street where I can get on it and not have to rev it all the way to 7k but I also want something that will do good at the strip. After getting a good rear and tires I wouldn't mind getting around the mid 11s

The TEA 220cc heads flow

0.100 69 52
0.200 144 119
0.300 212 182
0.400 263 224
0.500 295 247
0.550 306 253
0.600 307 257
0.650 309 260
0.700 310 262

the exhaust numbers are higher than what other head porting companies do simply because they use a pipe. I saw where someone tested them on a flow bench without a pipe and the flowed 210-215 instead of 260. Also the TEA heads use a 2.055 intake and 1.6 exhaust valve.

The AI 200cc heads

0.100 68.9 64.7
0.200 147.7 115.9
0.300 204.6 153.0
0.400 247.4 178.8
0.500 275.1 190.2
0.550 282.5 192.7
0.600 287.8 196.2
0.650 289.6 199.1
0.700 290.2 200.7

Now keep in mind the TEA heads are brand new trickflows ported for 1900 and the AI heads are stockers ported w/ a cam for 1975 plus I'd have to also pay to ship my heads there. I should be able to sell my heads for a couple hundred so the cost would even out.

so which head would suit my needs better?

Ai also has trickflows as well. With that said you should have no problem reaching your goals with the 200cc heads since I'm doing that on a stock shortblock. Your best bet would to to call them up and see what they say.

Well AI is also $500 more than TEA is when you compare their trickflow heads to TEA's

there is more to it than head flow numbers....you need to match a cam that is why Phil at AI has such a good rep.i really suggest you contact AI and go over your combination...i would not overlook LE either he has some real nice combos goin on!

well either way I am getting a custom cam so that really doesnt matter. Either way AI will make me a custom cam or I will order one myself. I will call AI when the time comes and talk to them. I'm just trying to figure out which head would better suit my needs

Talk to AI. After taking to Ron many times and a little bit with Phil, They will have my buisiness for any GM H/C packages, or portwork.

Nothing against TEA, but I would go with AI all the way.

The TEA's are not commonly used now days. Most people fo AI or LE for their heads, so i would go with one of the two for this build. Nothing against TEA, they make a great product, but i would put my money with AI or LE.

You should have no problem hitting your goal with a AI 200cc 383.

MY longblocks done it has LT4 trickflows that are ported I will let yall know the results .

I dont know who uses what but consider the valvetrain each has. I'd also consider things from a resale value stand point incase you ever want to go bigger or in a different direction with the car. Ported TFS's will go for more than ported stockers. TEA does very good stuff, so does AI and LE. You'll be happy with any of them.

You need to look at what is going into the head work for the price. I can't imagine TEA is doing much if any real work to the TFS castings considering the price of them bare. You are likely getting a whole lot more work done at the given price.

Also consider that Ai has other offerings that are more budget oriented if that is your biggest concern. Any of the Ai LT1 castings could easily get the power you are looking for. You should call them and see what they offer to reach your goals.

You and I can buy them bare for $1000... what do you think a distributor buys them for? I'd say TEA could get them for ~$800... so they charge $1100 more for valvetrain and porting... sounds reasonable to me. I wouldn't say "they don't do much if any real work". If they are truly advertised as 220cc... then they are doing a considerable amount of porting over the as cast version to get that volume. I am not saying more volume is better either, just that work needs to be done to get them there. TEA has a great reputation for head porting... I wouldn't question it.

That sounds about right. I posted this on a local forum and the fbody speed shop guy said these TEA heads are right up the alley for what I want w/ my 383 and will produce a nice torquey motor

The AI heads with the smaller runners would provide more low end tq IMO... if streetability and "around town" tq is what you are after, then I think the 200cc would do a better job than 220cc.

$369.50 per head (from my price sheet)

Our TFS heads are made from custom castings that we had made by TFS. They start with their 175cc ports and combine them with a reverse cool water jacket. This means our 220cc head has 45cc of material taken out once it's finished, so it is a considerable amount of work.

These heads were priced at $2195, but we reduced the price to help move some of these castings we had made, the consumer is the one who benefits.

These heads combined with an LT4 intake should make killer power everywhere.

Ill throw a monkey wrench into the works and suggest sending your stockers to Lingenfelter for the portwork and valve train upgrades..The head packages start at $1395 using your heads...I've got 13 years on mine and a baby Joe Overton custom cam 226/234 in my 383 and run the times in my sig at 3650ish raceweight...A true street car that is driven everywhere...LPE uses Manley severe duty 2.00/1.56 valves, double springs, titanium retainers, CNC ported and hand finishing and seemingly last forever...I'm still on the same valve springs they installed in 1995!

Brian, just out of curiosity, how many castings did you need to order for TFS to make custom ones for ya?

Its a toss up. Both suggested shops, have great products, and have TONS of experience in what they do. You'll just have to give each shop a call, and see what they can do for you, within your budget and time frame.
